Why do we have problems with setbacks?
We're viewing things through the lens of self-gratification vs failure.
Through the lens you will have failure FAR more often than you have self-gratification.
You're never going to win that game.
If you have a problem with a setback, it's because you're viewing it through the lens of attachment.
So naturally you will suffer. You will feel every bump on the road.
Everything becomes personal to you when it shouldn't.
