Hey running a coffee shop is a great business as long as you're not next store to Starbucks, or if your coffee is incredible. Besides, you don't have to code to run a business. Understanding how software is structured, what resources certain design decisions cost are valuable skills.

What language(s) do you code in? I hit the wall with c++ after 14 years of building sims/algorithms with it. Ruby/Python/javascript have opened up incredible avenues of hacking fun for me.
