This is such a loaded question, or rather a statement as it is presented here, but nevertheless an obvious inquiry.
It's a good one to ask yourself from time to time, even if your decision doesn't change once you are aware of the answer. You see, if you ask yourself often enough you will notice that more times then not the same answer may come up. If you find that that is the case you may want to take steps toward breaking out of that mold or working through your "this is what is stopping me" problem. Sometimes the answer is simple, sometimes it is complex, and other times it awakens uncomfortable truths.
Or maybe I am just over analyzing all of this. -tM
