Why does closing a deal feel like luck but losing feels like my fault?

Every deal you close, you chalk up to luck. Every one you lose, you take as proof you don't belong here. Notice what that does: it makes it impossible for you to ever win. Success doesn't count, and failure counts double. No one could feel competent under a scoring system rigged like that, and right now you are the one running it. The truth is that both wins and losses in sales are a mix of your effort and things far outside your control: timing, budgets, a buyer's bad day. A closed deal is not pure luck any more than a lost one is pure failure. The skill is real and it is spread across many attempts, not visible in any single result. Start keeping an honest tally. When you win, write down one thing you actually did well. When you lose, note one factor that was outside your hands. You are not making excuses. You are correcting a broken scoreboard that only ever counts against you.
