People ask me all the time, what are the most valuable things I learned working at Facebook. I worked there for three years as a PM → Director of Product. (1/x)

Here they are 👇

1/ Just because something is hard to know, doesn’t mean it is unknowable. Similarly, just because something is hard to do, doesn’t mean it can’t or shouldn’t be done.

2/ Rigor and quality of thought is critical to building great products. When you can build anything, structured thinking is essential.

3/ Understand. Identify. Execute. In that order, every time. (h/t @naomersg ) Too many people do it in reverse, skip a step, or do a bad job at any point.

4/ Crisp communication is the key to everything. (h/t @SadiSKhan)
