This, cannot be more true. After creating a few products of my own for the past few years, I learnt that if something does not gain popularity, it probably never will.
Conventional wisdom tells you not to give up, be persistent, persevere and keep trying. Sometimes all you need to do is to try something else instead. Once you have a hit, then go ahead and be persistent, persevere and improve.
Iterate on the hit, not the failure.
