Life is not what you make of itJust because I said life is what you make of it doesn't mean it has to be a me-centric purpose THS.
What if you decide your meaning/purpose or at least part of it is helping the less fortunate, community work, charity etc.? There are also plenty of careers whose main focus is helping others. IMO making the world a better place starts within ie. the individual working on making themselves fulfilled and happy as they will then be more effective when spreading the love.
Life dictatates to you what you can make of it
you don't have the kind of independence over life...
