Many people who think about starting businesses online don't even get started. The reason? A niche they'd thought would be great for them may attract lots of other entrepreneurs and before they get in the niche is saturated. What should one when they lose good business opportunities because they hesitated? Join the horde and hope that you'll do better than the others? Taking such risks when you know the competition is pretty stiff would most likely force you to make bad [business] decisions. This would cost you a lot. And when your goal is to make money, you don't want to lose it, right? Opportunities come and go and we can't always get everything we want. That's why losing one shouldn't make you give up starting a business altogether. There are plenty more business opportunities some of which could be better than the one you lose but you'll only find them if you stop thinking and looking back at what you lost.
