You're very interesting, you know that? :3 You talk like an artist. I figured you had some sort of classical training! I've never taken formal classes, so I find people that have really fascinating.
Ah yes, I can definitely relate to that. It was only a few years ago that I could only *ever* draw when I was almost or completely devoid of all sensation. Those were the worst of times, :p My forte is in comic books, so I guess when there's a story involved, it's a bit easier for me to translate images into my head onto the paper. Not to confuse "create" with "creative", however. I lack creativity in almost all regards. I'd be much better at drawing fruit if they'd actually get up and do something entertaining, you know? So I can definitely identify with your issue, at least to some respect.
I find that the best remedy is time. ;( But, realistically, changing your major was probably a good choice if you're actually looking for employment. Nowadays, graphic design and subjects to that effect are the best way to make money and use your creative side. Especially if you have a talent for it! Which clearly you do if your gallery consists of nonsensical doodles that were for fun. I'd love to see what you're capable of when you really apply yourself.
