The tempting move deserves attention to what it leaves undefended.

The attractive option is attractive precisely because it is showing you its best side. Whatever it gains is easy to picture, while the cost sits behind you in whatever you were holding and stop holding when you commit. Attention naturally goes to the prize rather than to the space it opens up, which is how sensible people make sudden, obvious errors.

Before acting on something that appeals to you immediately, name what it leaves unguarded: the time, the relationship, the fallback, the thing you were relying on. If you cannot find any cost at all, that is usually a sign you have not looked yet.
