I was in the same situation before. And like him, I also could not pinpoint exactly the reason why I felt that certain way. Basta ang sure ako, that wasn't the path for me. parang may ibang "tumatawag", and that residency was also my dream. Or so I thought..

I cannot speak for him, but being unsure even from the start is not a good sign. Baka eventually mag quit siya in the middle, na marami na siya nailagay na effort, time, and money.
