I am an INTP by nature — a pattern-finder. I approach a menu the way I approach a system: find the logic, remove the waste, identify what is actually doing the work. The applied nutrition training means I can look at a dish and think about both its cost and what it does in the body. The operations background means I care about whether that dish can be made consistently at 7pm on a Saturday with the team you actually have, not the team you planned for.
I have hired people I should not have hired, and kept people longer than the numbers justified. I have over-invested in kitchen equipment and under-invested in written systems. I have had the conversation with a staff member that nobody enjoys having. I have watched a business look operationally fine while the unit economics were quietly failing. I know what a POS report looks like when the business is in real trouble.
I write and consult about these things specifically, not as lessons-learned performance, because the specific version is the only version that is useful. The general version — hiring is hard, cash flow matters, build systems early — everyone already knows the general version. It helps almost nobody.
