@genome75 I am motivated by thinking of one specific user, usually someone I know in real life, who will enjoy my software once I've shared it with them.
Our 9 year old has been watching me develop a music app at various stages. One day she asked if I was going to release it on the net for everybody. ‘It looks good’ she said with two thumbs up.
As long as I can imagine my audience, I can feel their motivation pushing me ahead.
Even online-only friends will do.
