I'm always suspicious of people that say "life is what you make of it". It tends to turn into a hypocritical stance. Sure, do whatever you want with your life,
as long as it's something I approve of is the unspoken ending to that position. If my existence has no objective purpose why are you chastising me for being an unemployed, talentless, unpleasant person? If I want to be like that it's none of your business.
"Life is what you make of it" turns into "Life is what
I think you should make of it, that is get a job, have lots of skills and be nice to everyone". It's originally an open ended and technically correct position that is sullied by the limitations placed on us by the expectations of society.
If people 100% believed in that position they would have no objection to taking the lives of others. Life has no purpose, I can be a murderer if I want to. It doesn't matter if I killed someone, their life has no defined meaning either.
"Life is what you make it" is the most accurate answer to the question, for this reason:
If you present a rational argument as to why life has no purpose, that's what you've made it, according to your understanding. If you say that the purpose is to follow the precepts of a certain religion, based on God's authority, that's what you've made it, according to your understanding (because
you've chosen to accept the precepts as true).
According to my understanding, reality is playful, in the sense that it exists because there is no reason for it to do so. There are a multitude of purposes that human beings perceive, all of which have some degree of validity. Personally, my purpose is to grow in awareness and help others to do so where appropriate.
