Is anyone else considering of going for master’s/PhD?

I was preparing for competitive exams before I got placed last year and since then, I have been so swamped with work, I am barely able to take care of myself. I also think it’s partly because I wasn’t clear on the specifics - which uni to go to, what countries to target, etc. But I would like to resume studying and preparing for it, because going out and studying abroad is a childhood dream of mine. And if possible, I’d even like to get a PhD as I like learning in depth quite a lot.

I wonder if there are people in the same boat as me? Or people who did pursue master’s/PhD? What advice would you give someone who wants to pursue the same?
