Unconsciously inventing problems for ourselves?

[JohnClay]

My favourite advice about life is Mark Manson's "Life Is a Video Game - Here Are the Cheat Codes". He says things like:

......the game of Life is often quite difficult. You will face unexpected challenges and long periods of frustration. You will often struggle with self-doubt, feel overwhelmed by helplessness and loss....

Life is designed to continually throw difficult and unexpected problems at you. Life is a never-ending stream of problems that must be confronted, surmounted, and/or solved. If at any point, Life runs out of problems to give us, then as players, we will unconsciously invent problems for ourselves. Problems are what keep us occupied and give our lives meaning

That's happened to me multiple times when I've been in a manic episode and I'd end up creating problems for myself while feeling "high".

Do Christians agree with that bold part? How does it relate to God and humans? Is it part of the curse or our sinful natures? (you can ignore the part about being a player in a video game)
