If you think, you are doing a very important job, whatever you maybe doing.
You forgot the meaning of life.
It means, we are identified by the ends and not the means.
This is the cause of every bad experience in life. Sadness, stress, unhappiness, pain, depression, expectations, enmity, jealousy, anger, hatred, avarice, desire these things start to take control of who we are and the endless cycle begins.
Living is not about becoming something, it is about knowing who we are and do the best we can to live to our fullest potential.
