I didn't read the post just above mine until just now. And it confirms what I was saying and I had no idea that was true in what actually happened but it was what I susepected from everything I have read and everything I know about myself and other people.
Yelling is not the way to go. Eventually somewhere we have to find the resolve inside. If Bob encourages that resolve then awesome. Yelling leads to resentment, resentment will lead to failure eventually. Neither of them can be there all the time for the rest of our lives.
Whoever does a better job at helping to find that inner lifelong motivation is the best trainer. Because 'winning' is all about what we do with the rest of our lives not a 3 month countdown.
