The two themes I'm noticing from this list are "Lean heavily into a founders/startup community" and "Ask tough questions often". There are several bullets around coaching, bouncing ideas off of other (external) founders, leaning into internal cofounders strengths/passions, etc. I would generalize to say these things are not specific at all to the first 18 months at a startup (or startups in general). Leaders should be communicating with other leaders, teammates should be relying heavily on other teammates, all humans should seek counseling (via therapists, coaches and friends). A significant part of this process is knowing when to just smile and nod through unsolicited feedback/shitty advice. This is also totally unrelated to startups. To his second theme (ask tough questions often), it's just the common trap tons of startup founders seem to fall into. "We don't know if users will pay for this" should be one of the first questions you answer, way way before "How will we scale" or "What tech should we use". Managing worry is identical to asking tough questions (why are we worried about this and how do we overcome the worry). Mitigating risk is identical to asking tough questions (what could cause us to fail that is in our control). A part of being a leader is being unafraid to ask questions that need answering, even if their answers may be painful or scary. Most people aren't capable of looking hard at all of their possible failure scenarios honestly, and even less are able to objectively move forward with the findings of that examination. It's a tough ego game to play.
