I stopped thinking about that question long ago.
But now I have increasingly come to believe (through the study of spirituality) that the purpose of our lives is to make others feel lighter through our very presence.
And it is something you cannot force. It is something you have to build in yourself everyday, through study of good wisdom, meditation, contemplation of that wisdom, and so on.
No one wants to be a parasite but they end up becoming one when they are:
- always thinking what could go wrong
- bringing their bag of problems everywhere they go
- are perpetually sad because they think the world owes them anything
So much of life is about shedding your old beliefs, beliefs that drain more from you than anybody else.
The purpose of life is to live it.
