Bettering oneself can be a never ending project, because you can always be a better person. Therefore people often give up on this quest as they are envisioning an end to something that is eternal. There is no end result in the process of bettering yourself, no end stage satisfaction or (ultimately) fleeting achievement to feel you have conquered or aquired.
There are instead many results that you will experience and witness due to you’re being a better person. There is no great final feeling of satisfaction to be had, but rather a consistent sense of satisfaction that before long will begin to reside within. For the goal to this journey is simple; to be a better person than the one you were yesterday.
If one can commit to this, then one may become a better person; maybe even what we could call a truly great person.
The problem however, is that most people would rather be other things.
