I finished high school, spent 1 year full time at university, then 5 years very part time whilst I started a business. It's 18 years since I started that business and I still don't have a Bachelors degree, but it would be wrong to conclude that just because I never completed it I didn't get anything from it. Similarly I recently met someone who nearly finished their PHD, but has abandoned that to start a business. I am sure she got a lot out of the work she did towards that PHD even if she didn't finish it.
