Your cash flow, obligations, and buffers define capacity, while your nerves and patience define tolerance; mismatching them invites pain. Use a short worksheet: tally fixed costs, emergency reserves, income stability, and emotional signals during drawdowns. Align the lower number, and let opportunity grow from stability, not bravado.
Write down hard lines you will not cross: leverage caps, concentration limits, illiquidity exposure, and counterparties you refuse to trust. Then list early warnings like broken covenants, opaque fees, or leadership churn. Check these before any commitment. When two warnings appear together, pause automatically and seek disconfirming evidence.
