If you want to stay in business, satisfy customers. If you want to excel in business, delight customers.
Words not kept break more than a promise.
Focus not on who you are, but on what you can do for others.
Things that are obvious don't need to be talked about. Things that are missing, do.
If you want to interest people, make them think. If you want to inspire people, make them feel.
The shelter of excuses has a leaky roof.
