Define fit before you search
Write down the client, problem, budget, and delivery conditions that make a job attractive. A definition created before the search is harder to rationalize away.
Look for evidence
Prefer facts in the brief and client history over optimistic interpretations. Clear needs, credible budgets, and relevant history are stronger signals than broad enthusiasm.
Make skipping cheap
A good qualification system should make a no decision fast. Save your attention for opportunities where specificity can create an advantage.
