When anger is good

Dear Leader,
South Africa was playing a crucial rugby match against their arch-rivals Nieu Zealand. In the previous game, which South Africa lost, their captain, John Smith, was injured. He had to return to South Africa. He was furious. The reason was - he could not play in the next game - and he believed they would win...on a field where South Africa had never won. He wanted to be part of that victory. The team were hungry to win.
And they did.
Because even though he was absent, his anger showed that he really believed the team would win.
And it's all about believing in the team.
Regards
A Coach
