People have mortgages, five  3 year old kids, have to bring their sick kids to the doctor while working 3 jobs to make ends meet.So here comes this dude "Ohh why don't you figure out the fancy lifestyle you want to live and design your business around that".

I've seen well paid doctors never pay one bill on time and banquet waiters have $50,000 cash tips ready to use as a down payment.

I was told by my mentor, who is in his residency now, and by quite a few doctors that I have shadowed: "If you can see yourself doing anything other than becoming a doctor, do it."

That’s like saying you’re a doctor because you watched Grays Anatomy
