i'm a big fan of this quote! do what you love, get really good at it, and keep on practicing and getting better. i've always felt like i've wanted to learn and try everything, i'm usually of the mindset that i'll give anything thing a try at least once, but its always an awesome feeling to find something, a hobby, a skill, or a subject that you really just want to master. i felt this way in school when learning programs like photoshop and illustrator. i would (and still do) sit for hours blending photos together, adding vector graphics, tracing pictures with the pen tool and then trying to draw them free hand (with the track pad! eek!). some say obsession is unhealthy, but sometimes its just so good!
