@Wendz, I especially like 2. Living simply. I don't know exactly what it means for you, but for me is refusing to succumb to the pressure from corporations (advertising) and society (friends, colleagues, relatives e.t.c) to live life in a certain way. When you think about it, it's amazing how many things human beings do without thinking. Like moving to a bigger house because everyone else seems to be moving to a bigger house. Nothing wrong with that, but let that not be your motivation. Rather, do you have need for all the space? Can you afford it? Maybe I should add a 4th habit;
4) Thinking. Yes, thinking.
Learn first to treat your time as you would your money, then treat your money as you do your time.
