The whiner If you spill a cup of milk and you start crying, that doesn't solve the problem. Don't be a person who falls over crying every time something doesn't go your way. The truth is, most things aren't going to go your way most of the time. So, buck up, stop crying, and do what matters.
The negative thinker The world is filled with enough negative people. Be positive. I don't mean that you live like Pollyanna and avoid reality, but every single thought you think and word you say cannot possibly be negative. Think what can be done before you think about what can't be done. Open up your mind and heart and be free for good things to happen to you.
The master of all things Find out what you are made to do, what you love to do, what you have the talents and gifts to do, and do all of that and only that. Don't waste time trying to do a little bit of everything while at the same time getting nothing worthwhile done. Master you. Master your stuff. Do what you do with all your heart, mind, and soul.
