Taking care of yourself, staying in decent shape, eating well, and showing yourself and your body respect has an impact on both your ability to sustain the energy needed for the long hour's leadership requires and the way your athletes and staff view you.  It's a fact and taking the time to take care of yourself sends the right message to your troops.

Secondly, you can't expect to be lead others if you can't lead yourself.   You cant ask others to do what you will not.  Your athletes/employees watch everything you say and do and if you are not taking care of yourself they will see it.  Take care of yourself and you will garner more respect... it's true!
 
Send the right message. Put yourself in the best position to lead and sustain. Take care of yourself first and you'll have a distinct advantage over those who don't.
