Wow, thank you. =)) Are you even sure?
More than an obligation, I see life as a personal conquest.
Hmm, I can’t really give you tips on painting since I’ve only just recently started painting myself—I can only tell you that painting is something you have to put into practice, and you need lots of it because believe me, it’s frustrating. Try to paint something every day (or draw or doodle, at least). I try to create art at least once a day. I have a drawing tab (if that’s what you’re asking), and no, I don’t have a DeviantArt(?) account.
Tips for USTet? To be honest, I didn’t prepare for the exams back then. I just walked into my exam room and answered every question (not necessarily with confidence since I was relying on stocked knowledge). I guess you just have to visualize this goal in your head and constantly remind yourself of where you want to be. If you really want something, work hard for it. If you’re taking the exam for your dream course, look straight ahead and do your best. It will get you to places.
Good luck with the USTet!
