After graduating from a nanodegree program, Udacity now reimburses students half the cost. I'm in the full-stack program and this definitely motivated me to sign-up and motivates me to finish it, too.
Realizing that the benefits outweigh the costs (health and financial). In my case, the benefits would be avoiding the annoyances of glasses/contacts (cleaning them, reshaping the frames when they get bent, moisture, buying new ones) but given that the surgery might not result perfect vision or even cause new problems (halos, night vision, having to redo the surgery after ~10 years) it's not worth it. Plus, I'm less vain and more frugal now.
I've been wearing glasses since I was 8, got contacts when I was 13 and have been thinking about getting LASIK since it first became popular ~10 years ago. I have gone from wanting it really badly to now not wanting it all.
In high school and college, I wore contacts all the time because it improved my confidence. As I got older, I found myself wearing glasses all the time and contacts at the gym/social events, etc. As a side note, wearing contacts stabilizes your vision - your Rx will not change as quickly because of the short focal distance. This is a nice benefit because we spend so much time looking at screens nowadays.
Continue college so that you can learn and build up your business and technical skills. You will be able to create a better startup with a better set of skills, experiences and personal network - develop these while you're in college!
It's impressive that you've built a business in the first place. Try not to second guess your decision as you will probably go on to do bigger and better things :)

I also like the self-paced courses on Code.org: https://code.org/student/elementary
My kindergartner has access to Tynker through school. Maybe your school district has a license to something similar?
Good luck!
