Recovering burnt-out entrepreneur, should I get my MBA or just or refocus?

I’m (37) an artist turned entrepreneur coming off a CEO chapter and trying to be intentional about what comes next.

What I’m deeply passionate about is healing-centered creative work, marketing, and building spaces (online or in-person). I’m an art nerd with a knack for marketing and sales.

Right now I’m trying to decide between:

1. Going back to grad school (possibly an MBA or something adjacent) to formalize skills and open new doors

2. Refocusing and rebuilding independently, using my existing experience but in a more aligned, sustainable way

Im really scared of burnout. But also miss my work.

For those who’ve been through something similar:

Did grad school (especially an MBA) help after entrepreneurship, or did it just delay clarity?

If you chose not to go back, what did “refocus” actually look like in practice?
