Thank you for sharing your story/learnings. I didn't come across your blog initially. These specially resonated with me:

  I need a higher level of certainty than investors do because my time is more valuable to me than their money is to them. Investors place bets in a portfolio of companies, but I only have one life.

  Listen to what your users say, but believe what they do.

  From now on, immediate benefit: sell to the user. Long term benefit: sell to the boss.
