Turkish, having done a 3 year Engineering degree, I agree, the first year is boring. It would have got better had you stayed, but clearly as you say it wasn't really what you wanted to do.
Both learning to fly, and doing a degree (almost any degree) require a great deal of personal and financial commitment. Basically don't contemplate either unless you are pretty damned sure that's what you want to do.
I enjoyed my Engineering degree (so much I've been doing a second in my spare time over the last 5 years), notwithstanding the long hours, occasionally pointless maths, and somewhat laborious first year. There were other people who droppped out because it didn't suit them; well, it's probably better to learn that after 1 year than 3 or 4. But, a tough degree like Engineering (or law, medicine, physics, etc.) I'd suggest is no place for somebody who isn't interested in it. And frankly the degrees that aren't tough, probably would do nothing for your employment prospects anyway.
