It takes up to a week to start working after being off for a week?![]()
For many of the programmers that I know and work with, yes. I did say up to a week for some folks but it may just take 1-3 days for most. Especially with complex projects that interacts with dozens of different parts.
You just lose the momentum and have to figure out how to get it going again. It's difficult to just pick up from where you left off, just like it's difficult to resume writing a back when you stop writing it for a few weeks.
