To work smarter try using a timer - on your cell phone or use an egg-timer - and set it for 45 minutes.

"Mikrophonie I" (1964), for example, was inspired by hitting the tam-tam that hung in his garden with spoons, tumblers and an egg-timer.

If you want to dramatically cut down the time you spend writing articles, I suggest you get an egg timer or a regular clock and set a deadline for each article.
