If you're capable enough to go into business at the normal age for entering higher education then the 4 years you'll spend gaining real experience will put you further ahead of the graduate in year 5. University is good for learning independence and academic skills, and some degrees a necessary for certain vocations. But if you have the option and motivation you should probably just start work immediately. I used my degree to get my first job, I don't expect it to be weighted at all for my second job, in comparison to my experience in a job. On the flipside, university is an experience in and of itself and there is no real rush for you to start a job if you could spend 4 years surrounded by your peers learning more about the world and yourself without the pressure of a full-time job.
