What’s your purpose?

Curious to see what y’all think the purpose of living is as someone who doesn’t believe in a higher power. Back when I was Christian I felt like everything had purpose, which in hindsight I don’t think I fully thought through. Now as an adult, I’m trying to solidify my view of purpose and how I fit into the puzzle. So, what do you believe your purpose is, especially if life has no deeper meaning/purpose for existing. How do you create your own purpose?
