Using jealousy as motivation is healthy?

As a kid, I wanted to be an artist. I love drawing anything that's difficult.
But now as an adult, there will be competition. And whenever I see someone else's work, I feel deep jealousy and anger. I look at my works and they're always terrible. So many mistakes and so many jumbled things that it makes me sick.

When I look at many artists works, my main goal becomes "to be better than she/he is". I want to destroy their career. I feel the need of stomping in their art just to surpass. Everyday, my rule is to exceed my limits of drawing.

Is it normal this desire of humiliating other artists? This obsession that only makes me more anxious is healthy in one way?
