University isn't the only way... if, say your funds are extremely limited.
but remember that success comes from hard work, so even if you don't attend university you still have to work hard to success in life.
I know one person who doesn't attend university because of limited funds and now he's become more success than most university graduates.
What's most important I think is to choose the subject you like the most. Something you enjoy, something you
don't mind if you're not paid to do it.
