Learn from every mistake. Delight in the Details. Both heaven and hell are in the details. Even a fabulous gourmet meal, thrown on a paper plate and tossed at the customer would not be attractive. Pay attention to the presentation, the packaging, the delivery.
Little things count.
Avoid the cost of delay. Having reserves of space, time, money, energy and creativity allows you to make that call, sign a contract, form a partnership or start a new venture literally over-night. Or, to put it another way, take no significant risks, and always control the down-side. Having a reserve allows you to launch a website in a few hours' time with a tiny investment. And if it goes sour, you simply smile and move forward.
