Put together a realistic business plan, and continuously update it as conditions change, but stick with the plan.<br />
Remember the one fundamental to a successful business-no, two, no, three:<br />
1-Find a need in the marketplace and fill it.<br />
2-Work hard. make it your obsession.<br />
3-Do what you love, and you will never work a day in your life.
