Use the 2 minute rule at work. Can also be 1 or 5 minute rule depending on what job you have.
Everything that can be done in 2 minutes, do it immediately. I get a lot of questions daily, some can be done fast. Plan the longer ones for later.
Don't need to keep looking at a list and wondering where to start or how to get it done. Helps me to keep focus, clear my head and work efficiently.
