How do you guys deal with the feeling/insecurity that you're too slow, especially when working from home?

I never know if my progress is enough, or if the rest of my team thinks I'm watching Netflix half the time.

What we should do:
1. Find problem
2. Stop debugger
3. Change code
4. Restart debugging

What we all do:
1. Find problem
2. Forget about the debugger and change code immediately
3. Stop and Restart debugging

Having a boss who thinks he is an artist, designer, programmer, manager, salesman, pr manager, devops engineer and every project lead at the same time, never trusted anyone and reassigned tasks twice a day regardless of what you were working on right now. He was also unable to explain what he wanted or to set any meaningful goals. He also told customers we/he could do everything. One time, when we never made an app before, he accepted to deliver an iOS app within 1 week. ONE WEEK. THATS FIVE DAYS.
