GET OVER YOURSELF! Stop playing the victim and start playing the victor. You know why you shouldn't cry over spilled milk? Because 1. it's already on the ground and 2. it's easy to clean up. It's too easy to feel sad for yourself when things don't go your way. How about you challenge yourself and be happy...or rather optimistic in tough situations.
Try it! When you are in a tough situation and you feel like you want to cry, yell, and scream remind yourself that you are more than the situation you are in, smile, and move on to things that are in your control...like your attitude.
Instead of crying over spilled milk, clean it up and pour yourself another glass...after all it's just milk.
"When we are no longer able to change a situation - we are challenged to change ourselves."
