Mastery over science and math because (1) I already have a creative background in music and (2) I could do way more innovative stuff in music with a background in science.

Actually this kinda parallels my rationale for going to engineering school.

If I could use my scientific mastery to advance technology, that one.

Otherwise, I’d love to do art for Magic cards.

Mastery, I can use that mastery and my (admittedly just alright) artistic skills to program the games I want to make.
