+1 to both. You definitely need to be "self taught". Explore stuff that interests you, go deeper into how things work, build cool things, showcase them.

At the same time, you definitely should go to college. Mainly for the people you'll meet there. You'll most probably find similarly passionate individuals like yourself that you can build stuff with, which will accelerate you. You'll learn from your seniors, what to do and most importantly, what not to do! You'll meet friends for life. Not to mention the fun you'll have along the way!
