Control

Is life really all about choosing to exercise, or not exercise, self-control?

I mean, is my school career down to nothing more than self-control re: studying as opposed to say, time on Facebook or playing online scrabble or diligently checking the weather?

My kids, if I exercised more self-control about keeping our schedule myself, would they all be happy, healthy, wise and wealthy?

Diet - well, duh, if I had self-control there would be no diet.

Ditto exercise - although on this one I actually do have self-control.

Reaction to situations - if I controlled my own reactions, and refused to get flustered (say, when I get called on in class or when I am talking court), would the reaction eventually be submissive to my will? (Big stretch eh? But that basically is the "fake it till you feel it" idea isn't it?)

Depression - can I control this myself? I really don't see how???
