I am stuck between a hard place and a rock.

Here’s my dilemma, I know it’s a good problem to have but I need advice and insight from you more older and experienced gentlemen.

I am currently 24 years old. I will be entering my 2nd year of medical school. But I also have been running a small startup on the side. It has been growing rapidly and successfully. Its potential is there but its current cash flow is okay (positive but not great).

Should I quit medical school and go 100% into this startup? Or play it safe and become a doctor (but first study and intern for the next 5 to 7 years)?

Is a safe life and financial stability worth it? I need to decide before winter break is over.
