Before you can win the fight, You’ve got to be in the fight.

Concentrate on what will produce results rather than on the results, the process rather than the prize.

"Extra effort," in whatever form it takes (mental, physical, emotional), cannot be sustained without eventual damage and diminishing returns. There has to be a very acute awareness on your part as to the level of exertion and the toll it's taking on those you lead.

Many people erroneously think they have only one chance to succeed, and if they miss that chance, they are doomed to failure. In fact, most people have several opportunities to succeed.

To a winner, complacency and overconfidence can be destructive. To losers, desperation and despondency are just as harmful.

The dash helps to indicate that the two thoughts are intimately related, and it's less stodgy than a semicolon, which would have performed the same function (and who talks in semicolons?).

Your enthusiasm becomes their enthusiasm; your lukewarm presentation becomes their lukewarm interest in what you're offering.
