There are some battles that you may as well not fight. If you want to be successful, you must not only learn how to quit while you are ahead, but how to stop trying to get ahead when you feel that you are lagging behind. You are worrying too much, caring too much, winding yourself up far too much about a matter that does not really matter. Do what you can do, not what you can't. Work with what you have got, not with what you wish you had. And refuse to be drawn into petty disputes that ultimately mean nothing.
Hmmm, quite wise actually.
