BTW just a few more things to add about what Tony was saying about working in 90 min intervals, he means actual working with ZERO distractions, no phones on, no answering email, no facebook, no twitter etc. ACTUAL WORKING. And when you take your break, that doesn't give you permission to go to your distractions (mentioned above) .. your breaks purpose is to rejuvenate you. You set up times to answer emails, FB, twitter, phone calls etc. and you stay within those time limits as much as possible. Try it for a week, then push it to two weeks and so forth, then you are in a disciplined work mode and will get better results.
