I love your enthusiasm!

It's impossible to be considered the best artist ever by everyone. There will always be people who perfer a different kind of art and think a different person is better. However it's possible to be considered ONE of the best of a specific catagory.

Also becoming the best is a very far away goal. You won't be motivated to go for your goal after awhile because you will be progressing so slowly towards it. Try breaking it up into a ton of smaller goals. You will feel satisfaction after completing each smaller goal, motivating you to try more.

The most important part is have fun drawing. If you start to hate it you will be miserable trying to become the best.
For now try drawing ANYTHING, no matter how badly, and learn how to make improvements on it no matter how minor.
Also drawing EVERY day, even for only 10 minutes, and focusing on the drawing, you will improve trust me.
