Liking I imagine that as long as you're making money with a certain niche it shouldn't really matter if you like it much, correct? Knowing Ok, I know this sounds stupid but I've noticed a lot of people go after whatever the hottest niche is. Is it possible to be knowledgable of just about everything? That doesn't sound right to me. Do some people just wing it when it comes to some niches? Meaning they don't know much about it but try anyway because the risk is low and the reward is potentially high.
