Lol...most med students don't even have one job and those that do barely have time to work part time. Most people who have 1 business work 14 hour days for that ONE business. Yet you own and operate three and go to med school full time?
You must be a genius. What are the websites for all three businesses? I'm interested to see what you have going. I could learn so much with someone who is able to manage 30 hours of work within the 16 hours they're awake.
