Instead, you have to recognize that there will be great difficulties, and you need to be able to adapt, regroup, re-energize. Moreover, you must challenge yourself. You must be willing to take a clear-headed look at your plans, your abilities, the strength of your competition so you can respond accordingly. Great doubt is a part of a success, not necessarily an indication of failure. I remind myself of that every time I find myself at 3 a.m., sleepless, daunted by all the things we have to do to make our business a success.
Nothing succeeds without hard work.
I've seen hundreds of people with great ideas who have never made a dime. In fact, your work has just begun. Then, you have to figure out how to respond when a competitor brings in cheaper, foreign imitations. No great businesses are built on ideas alone - they take perseverance and long, hard work. Others will challenge your ideas and question your chances of success.
