Some opportunities are costly precisely because they are attractive.

The dangerous offers are not the bad ones. They are the ones good enough to override your judgment, interesting enough that you stop asking what they cost, flattering enough that refusing feels like a failure of nerve. Attractiveness is exactly what suppresses the calculation you would normally run.

When something excites you, slow down rather than speed up. Give it a night, and ask what you would have to give up if you said yes. Enthusiasm survives twenty-four hours. Impulses often do not, and that is useful information.
