I'll be graduating at 31, and will most likely spend the next 37 years working, and I'll be pleased that I did it. I wouldn't say you're 'behind' in life if you go to university later on, you're in the same place via the scenic route. I'd recommend it to anyone.
Your life before university isn't a waste, and in honesty you probably won't stay in the same career all your life anyway. Few people do these days unless they study medicine, dentistry, etc.
