Do what's right! Do the best you can and treat others the way you want to be treated because they will ask three questions: (1) Can I trust you? (2) Are you committed? (3) Do you care about me as a person?
We are not going to win because you have a new head coach, any more than you are going to fix a flat tire by changing the driver. We will win the minute all of us get rid of excuses as to why we can't win and stop wallowing in self-pity.
The answers to these questions will determine your success or failure. 1) Can people trust me to do what's right? 2) Am I committed to doing my best? 3) Do I care about other people and show it? If the answers to these questions are yes, there is no way you can fail.
I'd say handling people is the most important thing you can do as a coach. I've found every time I've gotten into trouble with a player, it's because I wasn't talking to him enough.
