What would be your biggest frustration fulfilling the role of a tech leader?

My team has 20 people and I find it really hard to keep them focused on perfecting the product. Seems like we are always responding to "emergencies" created by the sale team.

I was just wondering what other problems you were facing as technical leaders...

I also made a survey since I really want to understand what we are going through at the moment as technical leaders. I would really appreciate your help on that. Here is the link:

I've put up a report called Lessons learnt from “The Hard Thing About Hard Things” by Ben Horowitz which condenses the knowledge from the book. I will be sending it for free as gratitude for helping with the survey.
