I've had weeks where I do nothing, and then have two hours of real insight and solve a problem my team has had stuck in the backlog on for month/years in an afternoon.
I've had mornings where I browse HN, then take a shower, and suddenly realize the solution to a problem that ultimately brings my employer potentially millions in revenue.
At the same time, I can't perform these quick moments of brilliance for 8 hours a day, 5 days a week.
I've also had weeks were I put in long days quickly building a prototype needed to test out a new product idea, it's hard work but the results impress important clients and help everyone look good. But I can't keep up weeks like that for long without burnout.
The most import things:
- are you getting the things done you and your team agree are important, on time
- when you're involved with other people, where do the find you on the "oh god no" -- "oh thank god!" scale
If your team is on track solving the problems that need to be solved, and whenever someone pings you with a question or in need of help they leave feeling like you saved them a ton of time, it doesn't really matter if you work 5 minutes a day.
The inverse is also true. If people find that adding you to a project is a time suck, and things never seem to work right, it doesn't matter if you are putting in 70 hour work weeks.
