It's normal that all and everyone have the basic instinct or desire of want to be free, being unrestricted or unlimited by anything.
Somehow, if without correct understanding, some people are being disturbed and unhappy towards many existing inevitable restrictions and limitations of the physical body and the thinking mind in the world of selflessness and impermanence, not to say, towards many unnecessary restrictions and limitations that are created by many minds that are under the influence of ignorance and egoism to be restricting the freedom of thinking, actions and speech of all and everyone, under the great aspiration or ambition to be creating and controlling a world the way that they desire.
It's normal that all and everyone don't want and don't like to be restricted by some others for anything.
If without correct understanding and self-control, out of disagreement, dissatisfaction, resentment and rebelliousness, one might be behaving, acting and reacting in the way that would hurt oneself and/or others, and the surrounding environment, to express one's disagreement and dissatisfaction towards certain restrictions and limitations imposed by some others in the world of ignorance and egoism.
Due to ignorance, many minds might also think that self-control is a form of self-imposed restriction limiting one's own freedom of thinking, action and speech.
Many people not only don't like to be controlled or restricted by others, but also don't like to have self-control, time management or self-discipline, or be flexible on doing something that one likes to do but not necessarily at the timing or in the way that one would like it to be, where one needs to be making certain adjustment, adaptation and accommodation in order to be doing certain things that one would like to be doing, but then it's being restricted and limited by certain timing, duty and responsibility, condition and situation, weather and unforeseen circumstances. People want to be able to do whatever they want to do, at anytime and in anyway that they desire, or else, they will be disturbed and unhappy for not being able to do what they want to do at the exact timing and in the exact way that they desire, due to certain restricted timing, duty and responsibility, condition and situation, weather and unforeseen circumstances.
Self-control actually doesn't not contradicting with the freedom of thinking, action and speech at all. One is having control over what oneself want or don't want to think, do, or say, and not being a slave of ignorant, incorrect and hurtful thinking, actions and speech.
Self-control under the correct understanding towards selflessness and impermanence in the momentary limited life existence of a body and mind, and in all kind of names and forms, where the mind is not being over-powered by the desire of craving and aversion, but knowing what are the current limitations of the physical body and mind that are selfless and impermanent, while having self-control to be managing one's life and whatever oneself wants to do, without forcing and hurting one's body and mind, or generating disharmony in oneself and/or others, or the surrounding environment, as much as possible.
It doesn't mean that one is losing or sacrificing one's freedom of thinking, actions and speech if one needs to be having self-control and flexibility over one's thinking, actions and speech, or certain actions are being restricted by inevitable selfless impermanent changes and certain unforeseen circumstances, where certain things are not necessarily being done in particular timing or in particular way that one desires, but then, it could be done if oneself makes some adjustment, adaptation and accommodation towards certain things that are not in one's control to be exactly the way that one desires.
The inner flexibility of adaptation, adjustment and accommodation to move around and go beyond obstacle, difficulty, challenge and limitation in life, that can be developed through observing many of the observations in yoga or buddhism, enables the mind to transcend all kind of obstacle, difficulty, challenge and limitation, not by fighting against or removing the obstacle, difficulty or restriction, but to move around the obstacle, difficulty and restriction.
Not being determined by the obstacle, difficulty or restriction, but being flexible to make changes in accordance to the existing obstacle, difficulty or restriction, is real freedom, even though one doesn't necessarily doing something in the exact timing or in the exact way that one initially desired.
Being flexible to be making certain necessary changes or adjustments to adapt and accommodate certain inevitable or unnecessary restrictions and limitations is not limiting, or losing, or sacrificing one's freedom of thinking, actions and speech at all, just as many minds might think and understand in such way.
Being determined by the thinking and desire of "I should be able to think what I want to think, do what I want to do, and say what I want to say, at anytime and in anyway that I desire, without the need of self-control, time management and discipline, is freedom of thinking, actions and speech," while being disturbed and unhappy upon being restricted by certain inevitable or unnecessary restrictions or unforeseen circumstances to think, do and say at the exact timing and in the exact way as one desires, is no freedom at all.
It's the prideful ego that thinks and says, "I am weak, and I am being defeated by restrictions, obstacles, challenges and difficulties, if I am the one that has to make any changes and adjustments. I shall not adapt or accommodate, but to fight against all kind of restrictions, obstacles, challenges and difficulties, at all cost, until they move out of my way, to prove that I am strong, that I am stronger than them." That's everyone's freedom of thinking, desire, action and reaction.
The strength in yoga and buddhism is about being free from attachment and not being the slave of the passionate egoistic desire of craving and aversion, not being determined or disturbed by the selfless impermanent changes. Being able to do what is possible in the present moment, while let go or make changes towards what is impossible in the present moment, is real strength and flexibility. Physical strength and flexibility is nothing, if without inner strength and flexibility.
The ability of allowing one's mind to be opened to inquire the truth of everything, to conquer the impurities and restlessness in the mind, to free the mind from ignorance and egoism, not blind-believing, not blind-following, not blind-practicing, not blind-propagating and not blind-agreeing/disagreeing towards anything, and void of attachment, longing and craving, is the great freedom that cannot be given or taken away by anyone, even if one's organ of action and speech are being restricted by certain inevitable or unnecessary restriction and limitation.
Be free, by being able to be flexible to change, to adjust, adapt and accommodate, transcending all kind of inevitable or unnecessary restrictions, obstacles, challenges or difficulties.
