There is nothing you cannot start today. Every day is a new beginning, no matter what happened yesterday. If life got in the way, or simple procrastinating kept you from doing what you had planned, never mind. You can do it today.
The reason we always start IT troubleshooting with “Did you try a reboot?” is that it works. Starting over gets rid of superfluous zombie processes and reclaims memory. It works for your brain just as it does for your computer. But as your day wears on, you’ll find you work slower and slower. Email and other messages add background processes and use up memory, leaving you with little productivity left by the end of the workday.
That’s why you need to start with what’s important. Identify one task that has to happen today, and don’t open email, messaging apps, or social media until that is done.
