The first thing I look out for as a Coach is the Coachees internal engine. What this mean is that the coachee has an internal drive to move forward. Without this the coaches job is doomed.
Here's why. In consultancy speak, called the force field analysis, it means that the forces of resistance is greater than the forces of change. So we can only get forward momentum by the constant application of effort that is greater than the internal resistance. That is impossible to achieve without breakdown at some point.
Lets see what physics has to say here. If you have constant velocity, then the application of an external force produces acceleration. If you have acceleration then the application of an external force produces a higher rate of acceleration. This is important.
Ergo, it means you must help yourself first before anyone can help you. If you have forward momentum then someone can help you move further, move faster. If not your internal resistance will grind you to a halt the moment the external effort is released. The Coach cannot be with you 24/7, 365 days a week.
You have to move by yourself too. This applies to players, partners in business etc.
