How to avoid thinking about your love while studying?

[Melody]

Plan. Reasonably examine the amount of homework you still need to do. How long will it take to finish? What will take the longest? What is the most important? Organize all of your homework by most important, then by longest to finish.
Motivation. You won't want to finish your work unless you'll be sufficiently rewarded, right? Think of something that you really want to do; call your friends, watch a movie, surf the internet. Pick one that you can do when and only when you finish your homework. This will keep you motivated as long as it takes for you to finish your homework.

Food for thought. Eat some food that will help you think. Some examples are grapefruits, yogurt and oranges. These have a low glycemic index which doesn't stimulate your pancreas to secrete a lot of insulin, which causes your blood sugar to go up and down, along with your behavior.1 Foods with low glycemic indexes will help you focus. Keep some of these foods along with a bottle of water near your workspace to snack on while you work.

Music. Playing music, preferably relaxing, can help calm your nerves. It also gives you something to do and gets rid of the silence. Music also gives you some subconscious fun while not making you actively not working. You can always choose your favorite pop song and hum or softly sing along. As long as it isn't distracting you from what you should be doing. Try to make it instrumental so you won't get distracted by words. If you are studying for a test and not just doing work, however, studies say that you should make the environment as similar as you can to the test environment, so you may want to turn off the music if you can't listen to it on the test.

Breaktime. Set an alarm to go off every thirty or forty minutes. When the alarm goes off, take a ten minute break and do something to get your blood flowing, e.g. jog around the block, do twenty jumping jacks, do warm-up exercises. Whatever you do, don't make this break more than ten minutes, lest you get too distracted to focus.
Follow through. Get working on your homework. Turn off the TV, turn off the phone, sign off the instant messaging. The only reason the computer should be on is if you need it to research or write a paper. Turn on a radio, if you'd like, or pop in a CD. Keep the music quiet, though, so you don't lose concentration. Keep going until you have finished all of your work and earned your reward.

Think of consequences. Imagine yourself not doing the work and recieving an F for the whole class. Picture yourself being embarrassed by your teacher infront of all of your friends.

Log OUT of all social networks. Eg. Facebook, MSN, MySpace, etc. If logging out is too hard, put parent controls on the websites that you don't want to go on!
Lock doors, or tell family that you have to focus on homework.
Take break every hour, or whatever time you choose to replenish and re-focus.
Try to start homework a little bit early. (Don't procrastinate)
In a notebook, or piece of paper, write a schedule for your day or the order and time you want to finish each subject by.
Work at a desk with a structured chair. Not a bed, floor, couch, etc.
Turn on all of the lights in your room.
Keep the window open for fresh air.
Do not wear your pyjamas or such comfy clothes that you are going to fall asleep.
Have a prize in your head that you will reward yourself when finished.
Work with a friend or partner to keep each other focused.
Turn off phone or put in another room.
Try to have work space clear.
