Don't think about how much better you might feel. Its only temporary anyway... What, maybe 4 hours...
Dont think about how much more you could get done. Same thing, only temporary...

Find one of your kids and if you don't have kids, your significant other and square up to them and look them straight in the face. They are proabably going to look at you strangely but then imagine how they would look, if something "really bad" happened to you.
