Is that runway based on US expenses? If so, I’d seriously consider going abroad to a cheaper country. $24,000 saved is poverty level ~9 months in America but could last you a frugal 2 years in many places.

After that I’d figure out what you’d actually like to do, and use this opportunity to become good at it. 2 years is enough time to retrain in a good amount of careers, if you don’t waste your time.
