I wish you every success with it.
Food for thought... As you are bonsaiboy and not man, I have to assume there is a certain element of youth about you, so time is very much on your side. I hope that your passion for the art will burn bright for years to come. I will give you a small kernal of advice though... the material we choose to work on will determine the degree of success we achive. I never advocate for a newer learner to start with a seed, but with proper training, a seed can become a great bonsai. It has spent it's whole life in that pursuit. A young tree, not trained from the begining can generally have the potential of looking like a nice young tree in a pot, but rarely exhibits the grace I think you are trying to find within it. To achieve something credible (if that is your goal) it would be better to have one truly fine tree than 20 attempts that leave you wanting.
Discerning the true potential of a tree takes as much skill and experiance as knowing how to get it there.
When I first started, every tree was an opportunity for me to practice my craft. Now I can go through entire nurseries and collections and find nothing which has the potential I require. Because every tree is an obligation, and a promise of my time and effort I put the bar fairly high compared to most. I also recognize the value of being willing to buy nature's or someone else's time. There is a misunderstanding of what constitutes being a bonsai artist. The mantra seems to be "I'm going to do it all my self, and so I'll take this twig and turn it into a treasure." as if that is somehow more valid. These same people pour over bonsai books and magazines and are inspired to want to create the same things they see, which is completely impossible for them because they deny themselves the one thing those other folks do not.... material worthy of their vision.
As I said... this is just food for thought. Not meant in any way to discourage you from your current path. We all have walked this path to greater or lesser degrees. But at some point, you'll grow out of material of this nature. I hope the rememberance of this conversation will help illuminate the path in a different direction for you. Some people never decide to depart from the first path, and that's fine too.. there is room enough for all, but somehow I think you'll leave it sooner than most.
