I think the reality is that it's never been a better time to be an entrepreneur, it's never been a better time to work at a startup. You work at a really intellectually free environment, you get to work with people who are like-minded, it's very energetic. It's wonderful.

The goal of a private company is, first, zero to one. Get past the product market fit, figure out whether people actually care about what you're trying to build and someone will pay you money for that. That's the zero to one problem. So scaling, one through N, is figuring out can you do that at scale and how big is the scale. And when people pay you more than what it costs for you to make it, does that equation end up leaving you with money left over, i.e. profits.

It's OK, by the way, that it takes 10 years for you to make "money." Since when was it that being in your mid-30s to make a few hundred thousand dollars or a million dollars was like egregiously unfair? I think we have to have a sense of perspective here. We're all going to live into our 80s or 90s. So what is everybody in such a rush for?

I would tell startups to just keep your head down, keep building. Your contingency plan, if you have one, should be because you are still spending more than you make and you still don't have a line of sight for that J curve. That is the most important contingency. Because otherwise you are betraying that equation to your cofounders, to your investors, to your employees and to your customers.

If you're trying to get to profitability by lowering costs as a startup then you are in a very precarious and difficult position. You need to grow through profitability.

The half-life of companies is shrinking. So in the same ease in which you can start a company today to disrupt an incumbent, you have to also realize that somebody will do that to you as well just as easily. So if you're not just going to get on top but stay on top, that will require a real prepared mind across many companies.
