When do we get yo call ourselves ‘Successful‘?

Im a 28 year old First gen Doctor,doing my second year residency in Gen Surg in a GMC. I come from a pretty low middle class family and i was the first doctor in my family.

Neet UG happened -Got into mbbs-finished mbbs-worked a bit-Neet pg cracked- Goy into GS.

My father lost his job pretty early on so ive been providing for the family since a while now.

We live in a rented house ,My mbbs even tho was done from a GMC still was done with a loan- now that emi is being paid monthly along with all the other expenses happening.

At the end of the month,im basically left with nothing-even though im not spending a lot on fancy stuff.

All my other friends working in other fields have seem to have achieved so much more when i think about it-most of them bought a house, some married,some atleast are having a decent standard of life. And here i am,struggling to even buy books for myself.

I love surgery,i love everything about medicine in general but things like this makes me wonder sometimes,if i‘ve made the right call. I wonder if i’d ever become successfull in its right sense.
