That was my mom's constant mantra as we were growing up. When we moped around, said "it's not fair", or bemoaned our lot in life, my mom would say "Get Over It".
Not that she didn't do the things a mom is supposed to do. She listened, she advised, she hugged, she cried with and for us, but when it came down to it, her philosophy was to get over it. Not that it fixed everything, but you had to get over it (no matter what it was, or how serious it was) at least enough to continue functioning in life, and move on with it.
She came from a really rough life, and that is how she dealt.
What phrases or philosophy did your mom (or dad) use about life. Did you carry that on? Did you agree with it or not?
