The most important part is to just pay attention to how your current setup affects your mood, creativity, focus, etc. It'll be way easier to adjust once you're in tune with that.

It's really easy to end up on autopilot with the structure of your workdays, only to notice that it doesn't work for the current project all that well. Getting stuck on the 'nothing' approach can be just as bad as getting stuck on a 'hundred tabs' approach if you're just doing one or the other because you've always been doing it.
