This is an amazing list.. Several of these things are things that I have noted to myself in hindsight after helping to start, grow, and then watching a company fail.
One thing I’d note is that it is easy to let an abundance of #2 (trust) stop you from following #3, and delaying firing someone. I second the concept that delaying the firing of someone isn’t in the long-run doing ANYONE any favors.. I’ve worked where the boss almost put the company out of business by trying to be the nice guy and not firing people when appropriate, but once he did, even the most bitter of the employees let go are eventually happier for it, and have moved on to better, more appropriate jobs for them.
