The ironic thing about investing in your productivity is that it’s almost impossible to do when you’re slogging it out in the office trenches. There’s simply too much to keep up with—meetings, email chains, and project deadlines included. For this reason, the best productivity tactics are the ones that require you to step back and remove yourself from your work so you have the mental space to think critically about how you should approach that work differently. That way, when you return to work, you can do it more intelligently, instead of just harder.
