Belief in devils necessitates belief in an opposite that can recover the good things. Everyone has bitterness and trauma, no one gets exactly what they want, how they want it with no pain or suffering.

When I get to feeling bad I make something up. I'm creative/imaginative and strong-willed so can wrestle my thinking around to where I'm facing a different direction. I have so many things that can be worked on/fixed that I never run out of directions to face. If I can't solve "this" problem at the moment I twiddle with a different one for a bit, see if I can make headway on it. It's like doing a crossword puzzle where I get one answer and that helps me with a connecting one, etc. and sometimes I ask people around me for help and they help with one and eventually the puzzle will get solved. Life though is a really large puzzle :-)
