For most of the early hires you make in a startup, experience doesn't matter very much, and you should go for aptitude.

One thing that often disrupts momentum and really shouldn't is competitors.

To get the very best people- they have a lot of great options, and so it can easily take a year to recruit someone.

If someone is getting every decision wrong, that's when you need to act, and at that point it'll be painfully aware to everyone.

If you don't love and believe in what you're building, you're likely to give up at some point along the way.

You should always know how you're doing against your metrics. You should always have a weekly review meeting every week.
