If you look up the definition of the word "rationalize", you get this:
ra·tio·nal·izeverb \ˈrash-nə-ˌlīz, ˈra-shə-nə-ˌlīz\ : to think about or describe something (such as bad behavior) in a way that explains it and makes it seem proper, more attractive, etc.
Well, heck yeah! Why wouldn't you do that?
It is the phrase "turn that frown upside down" in a nutshell.
That is how I choose to look at most things...
I realize that I am not the brightest bulb in the pack, but I sure do try my hardest at every stinking thing I do.... Effort is something I am good at! I choose to put effort into making everything look more attractive. Attractive is so much better than not attractive.
Give it a try. It is something you must work at, but like all habits, it can grow on you ~ for the best!
