Startups

If you're the CEO of a fast-growing startup, the mistake you'll make in the next year that you'll regret most will probably be a hiring mistake. Possibly hiring someone established, which you'll feel you should do now you're getting big, and which VCs will strongly encourage.

If you notice something at your company below standards and don't fix it or make sure someone else does, you have set a new standard. Complaining about it does not count as fixing it. If someone gets upset/tells you to stay in your lane, they've set an even worse new standard.
