Most of my ideas I am initially excited about. If I'm lucky then I may even be genuinely positive that the idea is "going to work". But, just like clockwork, I eventually begin to doubt the idea and usually end up dropping it. This usually occurs the day or so after the inception of the idea.
Usually, my reasoning for dropping an idea is that it seems so useless and minor in the grand scheme of things. I try to picture people using the product and it actually making their life better in some way. This is obviously not an easy thing to do.
I think that over the years I've trained myself to be my own worst critic. I'll let myself get engulfed in an idea right away, but then I always take a step back and criticize the unpolished idea to the point where I convince myself that it's useless.
What are some things that help you all remain optimistic and excited about an idea?
