I am a stubborn mule and love the challenge (as much as it frustrates me) . The fact that I haven't developed anything to brag about and frankly don't really know how to just yet fuels me to keep going with ferocity. It's when I'm able to turn to those whose trees I respect tremendously and say "you call that a bonsai?", that will be closer to the time I lose interest. Luckily, I am nowhere near that.
