It is unwise to do things out of self-preservation, just to prove yourself.You will merely evolve in proving yourself-- to whom?
Lack of self-confidence will pull you to spending more energy for self-interest hence wasted time that should be spent for selfless ventures.
Find time to dedicate an hour of your time for other people outside of your greed and envy. Be kind and reachable at least for a short time if you could not afford to make it a selfless sustaining advocacy.
