Hello,
I applied for 1 cycle after undergrad, got waitlisted, then went to do my masters, applied again after masters, again got waitlisted. Finally I was convinced by my PI to do a Ph.D in which I could have a "fruitful research career that is high-paying and rewarding." Since I had a good experience with my masters, I committed to doing a Ph.D, thinking that if I become a MD afterwards, this Ph.D will help me get into a specialist field in medicine.
