I do it.I'll usually start by over-commiting , like a big project or a show,Jumping in the deep end you find your "voice" quickly and deepen as the need arises. A great painter Paints.

What Christopher said . . . and I'll add:

My philosophy, for the longest time, has been that to reach a lofty goal you need to set ridiculously high goals. It's best, I've always thought, to assume that you will never reach your goal and therefore if you strive only for a "realistic" goal, then you will never reach it. Always be unrealistic in your ambitions. Always overreach. Only by overreaching can you advance.

When I first went to college and started taking writing classes, I decided I would break every rule I possibly could. Any rule I found I would try to break. You learn things very quickly this way. I've also always rejected the saying that "in order to break the rules you must learn them first". This is only partially true; if you wait too long, you'll never, ever find your own voice. Finding your own voice is the most difficult thing in writing or any other art form, and you must start the journey as early as possible, because it takes a long, long time. But it helps to overreach, to experiment, to break rules, to go as far as you possibly can, to conceive ridiculous ideas and then see if you can put them into practice. Because . . . only by DOING can you learn. A textbook will not teach you how to create art. Anybody can learn how to draw, or write, or paint, or sculpt -- as far as the craft goes. But ART cannot be taught. It must be learned through practice, through feeling.

Open yourself up, take down all your walls, sacrifice yourself, commit artistic suicide every chance you get. That's how you learn, and that's how you find out your own voice, and advance. Do not be afraid. If something you want scares you, then terrorize yourself. You'll get over the fear.

Also, it helps to be aware of artists who are ridiculously confident and ambitious, of artists who overreach -- that encourages a person. Go out and find out all you can about all the artists and artwork in the areas that interest you. See what's possible, what's been done, and learn from that, and then go ahead and try out your own ideas, try out the most ridiculous things you can think of.

If it helps: Don't show your work to anybody. That's one thing I did when I was younger. It frees you up, you don't have to worry about other people's judgment.
