We often think of discipline as being trained to conform by use of punishment, an unpleasant experience of being dominated by another person or thing to take away our will however what if the opposite was true.  What if the consequences of us following our "feelings" was the punishment.  What if our changing and fleeting feelings were robbing us of what we really want, to be happy, healthy and fulfilled?  If we change the way we look at discipline and see the freedom available to us then being self-disciplined can become easy.
