Post-Grad or Work Ex? Looking for guidance.

I'm 23 and working in Bangalore in the Founder's Office role at a startup. I aspire to be a Founder someday and run my own business, but don't have an idea that I am very passionate about right now. I have 3 years of work experience as I started working alongside my college. I am really confused whether I should consider Post-Grad or continue working. And if PG, then from India or outside. Any guidance or points to consider would help.
