What is the purpose in life?
I stand by the idea that we create purpose as opposed to a purpose creating us, so it really depends on who you ask. Some just want to enjoy life, some want to succeed, some want to make the world a better place or be remembered for something, some want to continue their lineage, some want to have children who can do one of or multiple of the above.
I would probably fall into the all of the above category, but I don't think I've reached the point in my life yet when I've settled on an answer to such introspective questions. :P
I'll probably never settle on a purpose for myself, so I just try to do the best I can in everything and hope it's enough. I suppose I'd like to be remembered as having done something that affects people outside of the usual circles of family and friends that everyone affects, but I'd also be okay with not doing that.
tl;dr idk man.
Is it possible to find a purpose without religion?
I'm an atheist and I feel like the only people who think this are some religious people. I personally feel like life actually becomes a lot more purposeful without religion. With an afterlife this world just becomes a stepping stone, whereas in a world view without God, our time is limited and we have to make the most of it to impact the people in the future who will have their own limited lifetimes.
I like how Ricky Gervais put it: we have nothing to die for but everything to live for. For the religious, it seems more like the meaning of life is simply to die above a certain threshold to get to the next stage, if that makes sense.
How do you find your purpose? Or is there no purpose in life? If there is no purpose in life, what do you do?
Pretty much explained above. Life doesn't have inherent purpose but we can give it purpose.
