Great thread andkon. I'm essentially a single founder, but I have a contract dev and there is always so much to do. There is a lot of good advice here already, but to me, the marathon analogy is best. In other words, take the long view.
I know a man who built an engineering company up from nothing to a billion dollar exit over 30 years. I'm in week one of having my app available to the world.
Am I in a hurry? No. I have a long time to build a business. I cannot live or die each DAY/WEEK/MONTH based on users who joined, or users who left, or any other metric. Good Luck!
