I can definitely see where you're coming from, but trust me, it is not that foreign at all. You can even start experimenting and mucking around in Photoshop right now! I personally thought there was a lot more freedom in the digital world than the physical: in terms of convenience.
I suppose you'll be bringing a laptop to those classes then? If you find yourself still yearning to use your own hand, I recommend buying a Graphics tablet!
For career, a software developer sounds cool, but I'd honestly would like to develop my own thing as well. So one thing I'd hope to achieve in uni would be to attempt at one of my own ideas - I'm sure you yourself or others have thought of this as well!
However, besides that, I have no idea, things can change a lot in 3 years haha
How about you, what would you like to do? Future Jonathan Ive?
