We are not happy generally because we are not happy about ourselves; not happy with our lives, with other people and the happenings in the world. We are discontented about something or everything. We have lots of fears and worries. We want to enjoy life but we don’t really know how?
We cannot even please our own self because our mood and wants are changing all the time, and thus it is impossible to please everybody in this world of diversity.
Most of the time, we don’t know what we really want and don’t want.
We are afraid of losing "this" if we decide to choose "that" or vice versa. Indecisive is a common reason why people are not at peace, being troubled and unhappy in life.
And egoism is the main cause for all the unhappiness in us. Anger, hatred, jealousy, greed, arrogance, attachment, craving, aversion, low confidence, low self-esteem, depression, fears and worries are derived from the ego.
We are not happy because we don't have wisdom or right understanding at the moment. It doesn't matter if we had went through higher education or had read a lot of books and had attained lots of various certificates or having many talents.
When there is wisdom, there is no unhappiness or depression.
May we all attain wisdom in this life now and be happy.
