- close your e-mail program
- close the office door
- close all applications you are not using on your computer
- do one thing offline: keep an offline to-do list and check each task when its done
- drink high-quality coffee while working
- do not use the computer mouse - the keyboard keeps your attention at work
Try it out the next time you are noticing that your are sliding away from where focus should be; it helps for me at least!
