In the opening of Terry Garey's The Joy of Home Wine Making, She quotes her grandmother Garey during an earthquake : ''Do the best you can and don't worry!"
One day I decided that all of my worrying was like little pleas to God to keep bad things from happening. It suddenly occurred to me that if I were on the receiving end of that, it would be really annoying. So I quit.
I still feel I need to plan for the future and have contingency plans though.
