Thanks for the thoughtful comment! This is my first try at entrepreneurship. I'd be lying if I said that I'm always sure it was worth it. Most of the time, though, I really think it is, regardless of if it's commercially a success or not. Probably sounds corny, but for a product to work commercially, it needs to have both passion from your end and usefulness on the other. I think if there's no passion, it's probably not going anywhere and even if it does it's not worth it.
