To be a good manager (hardly a complete list):

1.) Be willing to turn away money if it means a bad deal.
2.) Treat each customer as a true partner.
3.) Treat each employee as if they were customers, if not better.
4.) Give random perks to employees -- so not an Xmas bonus so much as a random bonus for a good job, or the proverbial free lunch. Doesn't have to be big, just needs to show you're watching.
5.) Be willing to turn away money if it means a bad deal.
