Usually, when I have a "good" idea, I set myself a big milestone and work extremely hard and focused towards it. Its usually new tech or in a new domain so I do all the research and get the workflow from beginning to end working. The problem is, this milestone is usually 85% of a prototype and 20% of a product. And at this point all the fun and motivation is gone and "launching" was never so interesting to me as "getting this finally to work". So usually I commit my code at this point, push it and go do something else. :) Honestly it only ever worked once for me and that was when I showed the prototype to an audience and they kept me motivated to keep going but I have a feeling this is not the best way to go about it.
