I've started two businesses without going to graduate school. I'm more of a hands-on learner, so I wanted to spend the two years actually starting a business rather than thinking about / learning about starting a business.

The caveat is that my first business was part of a franchise system. Working within their system ended up being like a hands-on MBA program for me, with the benefit that after two years I had a viable business instead of no business and lots of debt.

There are plenty of good reasons to go to graduate school. And people do come out of graduate school with a strong network. But that's not a good reason to go. Plenty of people who haven't been to graduate school have strong networks.

I recommend being clear about what you want to be doing, and determine if graduate school will help you get there faster.

If you want to further discuss how graduate school might (or might not) be in line with your goals, I'd be happy to set up a call.
