Sense of Accomplishment

Is there anything better than the feeling of self accomplishment?  Putting your mind to something, investing time into it, and coming out on top or just finishing whatever it is you set out to do.  The bigger the task the better the feeling too.  It really makes me wonder why I don't do more in my life.  I thoroughly enjoy the feeling of accomplishing things, so why am I not proactive in completing the tasks that are right in front of me.  I honestly don't know; I could say it's laziness but who isn't lazy, so I think it might be something else.  All I know is I need to start doing more and thinking less.  The more I think about it, the less likely I am to actually do it (That's what she said).  Oh well, tomorrow is another day full of chances to accomplish things, and after tonight, I'm looking forward to it.
