I'm going to start with Print On Demand products. This thing is great because you can create your brand and target on what is hot on the market now a days. However, in my opinion, everything depends on you, not on your niche store or general store. Everything starts within you. If you won't give up until u'll find your winner product - you will win the game. Do you know this famous quote: ,,Quitters never win, winners never quit"? Use that once you are feeling upset, feeling that you are giving up.
