Boss: I can't promote you because you didn't have an impact on anything important. Dilbert: How can I have an impact on important things when you put me on unimportant projects? Boss: That sounds like an excuse. Dilbert: What's the difference between an excuse and a great reason? Boss: It depends who says it. Leaders have great reasons when things don't work out, but losers just have excuses. Dilbert: So... you can turn my excuses into great reasons by promoting me? Boss: No, because I can't promote you. Dilbert: That sounds like an excuse.
