Batch your work
The complementary tactic for cutting off interruptions is to work in batches. Research has shown that separating the day into blocks of time devoted to specific tasks can help people become more productive.
On the desktop, you can use timers to set aside a block of time to work on something. Try setting it anywhere from 25 to 60 minutes. Different people have different lengths of peak focus time, after which forcing yourself to continue actually results in shoddier work.
When the timer rings, give yourself a 10- to 20-minute break, then start the timer again for the next block of work.
This can work not only in your office, but it can pay off in your personal life as well. Imagine when you’ve consciously decided that in the next one-hour block of time, you’re not going to do anything but play with your kids. No interruptions allowed, including checking your phone. You’ll probably play happier.
