No. I refuse to live a life without hope. I would rather believe a lie than live thinking this life is all we have.

That's valid and I totally respect that but I'm asking for any tips that don't involve religion / for someone who believes what we see is what there is

Escape through drugs and experiences until death. Eat, drink, for tomorrow we die.

I wish I could have that kind of faith, but I always get stuck on "how do I pick which lie"?

Think of faith as a choice. Then weigh your satisfaction after exercising it.

Perhaps I could go off your username, and put my faith in pizza. I'm generally pretty satisfied after pizza.
