You need to give customers really compelling reasons to buy from you.
Without good finance, you fail.
People do their best work when they're part of a really great organization.
If you want the staff to give great service to customers, the leaders have to give great service to the staff.
If you want great performance from your staff, you have to give them clear expectations and training tools.
Successful businesses do the things that others know they should do, but generally do not.
To get to greatness you've got to keep getting better, all the time!
Success means you get better problems.
Whatever your strengths are, they will likely lead straight to your weaknesses.
