Life Purpose

One could be lost because you couldn’t define your life purpose? Everywhere I turn, I read or am told I must find my purpose to be happy. What I mean by “life purpose” I am talking about defining a specific action that you can dedicate your entire life to. Purpose means doing something that has a positive effect on others, giving or sharing something that has a strong emotional outcome on yourself and others, or working to change a social structure that might not completely happen in your lifetime.
