Yes, you can let life get to you if you aren't careful. It is really easy to allow yourself to get defined by the tough stuff. We all have our crosses to bear, and sitting around feeling sorry for yourself just feeds the beast.
My parents have been doing it for years, and as a consequence it is their adversities that define them.
That's not for me!
Accentuate the positive!
That is too sad @matbaker :(
And yes, I am definitely on your bus! haha
