There is no substitute for paying attention... here are Five tips to improve your attention/concentration/focus/productivity:
F = Five More Rule
There are two kinds of people -- those who have learned how to work through frustration, and those who wish they had. From now on, if you're in the middle of a task and tempted to give up -- just do 5 MORE. Read 5 MORE pages. Finish 5 MORE math problems. Work 5 MORE minutes.
O = One Think At a Time
Quite self-explantory, isn't it? We know the theory, now let's put in practice.
C = Conquer Procrastination
Don't feel like concentrating? Are you putting off a task or project you're supposed to be working on? That's a form of procrastination. R. D. Clyde said, "It's amazing how long it takes to complete something we're not working on." ~ Every time you catch yourself doing something that you are not suppose to be doing (facebook, twitter, 9gag) quite it right away, and get back to your homework/work.
U = Use Your Hands as Blinkers
Give multi-tasking a rest. Focus in one task at time!
S = See As If For the First or Last Time
uhm... maybe not very useful but it says: Want to know how to be "here and now" and fully present instead of mindlessly rushing here, there, and everywhere? Frederick Franck said, "When the eye wakes up to see again, it suddenly stops taking anything for granted." Evelyn Underhill said, "For lack of attention, a thousand forms of loveliness elude us every day."
