5 ELIMINATE ALL COMMUNICATION
While you're working, turn off the phone, and don't check your email. Hang a sign that says, <<Do not disturb>> if necessary. You don't have to do this this for all of your tasks, but at least do it for the more delicate items.
6 BATCH SIMILAR TASKS TOGETHER
Do all of your E-Mailing at one time and make all your phone calls at another. You'll waste more time by jumping around from task to task.
7 SET A TIMER
Even if a task might take hours, starting it will seem easier if you give yourself 30 minutes to get as much done as you can. A time limit helps a lot of people concentrate and work better in certain settings.
8 SET TARGETS
For example; if you have to make cold-calls for your sales job, tell yourself that you're not getting up for any reason until you've made at least 100 calls. Regardless of what happens, refuse to stop until you hit your target.
