This quote from Philip K Dick seems relevant:

Reality is that which, when you stop believing in it, doesn't go away.

"Being honest with themselves about whether what they are doing is actually working or not" and "Having the courage to go on when nobody believes in you" are opposites.

>Figure out why you were put on this earth.

Who is responsible for this mess? ;)

Such a great synopsis. The things that are easy to signal (landing page, presentation deck, logo, etc) have never been the make-or-break aspect. The part that's always been hard, that remains hard, is that a business must solve a problem for people. Even B2B is solving business problems for specific people. And people are a difficult, difficult problem to solve.
