There is a difference between ignorance and being spontaneous...

I know I might sound weird, but I know theory (I teach music) I think it is a fantastic tool, that it develops things that you wouldn't have come up with if you were ignorant and everything, but let's take the painting example:

One guy is an amazing painter, he only has the money to buy red and blue. His art is so cool everyone loves it, buy it and he becomes rich. He can now have all the money he needs. So he paints even greater things, with awesome colors...

Another guy paints stuff but he is mediocre. He wins 20000 at a lottery. He then buys all the colors, and does paintings very colorful. Other painters love the colors on his paintings, they wish they could do the same with theirs.

The difference between the 2? The first one has something to say, and colors (theory) expands the realm of possibilities. The other one is just some John Smith, and his paintings remain what they are, colors on a canvas (or in music, exercices, or shred music, among others)

I hope I have made my point clearer...
