A food truck that lasts isn’t one with no slow days. It’s one built to survive them.

Durability is not the absence of bad stretches, it is having been built with bad stretches assumed. Everything has slow weeks; the difference between the places that close and the ones still there in five years is usually margin, low costs and a plan for the quiet month. Hoping for no slow days is not a strategy. Designing for them is unglamorous and nearly always what works.

Look at whatever you are keeping going and ask what happens in its worst week. Then make one change that would soften it: a smaller commitment, a reserve, a version you can run while tired.
