A life of frustration is inevitable for any coach whose main enjoyment is winning.
It's not pleasant when you lose your whole football team.
Before you can win a game, you have to not lose it.
On every team, there is a core group that sets the tone for everyone else. If the tone is positive, you have half the battle won. If it is negative, you are beaten before you ever walk on the field.
Never make a major decision based solely on money.
If you want to win, do the ordinary things better than anyone else does them day in and day out.
