Make a "to do" list every day. Put things that are most important at the top of your list and do them first. Use your agenda to track all of your tasks. And don't forget to recognize and reward your accomplishments.
Use time wisely. Taking time to think and plan is time well spent. If you can get some reading done while waiting for an appointment, for example, you'll kill two birds with one stone.
Know that it's okay to say "no." If your friends ask you to go out on a Sunday night and you have an assignment due for class the next morning, realize that it's okay to say "no." Keep your short- and long-term priorities in mind, and don't feel pressured to drop your plans to please your friends. Planning in advance to spend time with friends and family can help, but first you must be convinced that your priorities are important. Once you are convinced of that saying "no" gets easier.
Work smarter, not harder. You'll study more efficiently if you figure out when you do your best work. For example, if your brain handles math better in the afternoon, don't wait to do it until late at night.
Review your notes daily. You'll reinforce what you've learned, so you need less time to study. You'll also be ready the next day if your teacher calls on you or gives a pop quiz.
Get a good night's sleep and eat healthy. Running on empty makes the day seem longer and tasks seem more difficult.
Are text messages, calls, computer usage or video games proving to be a distraction from homework or time wasters? If so, manage your time so electronics don't undermine your academics.
Don't sweat the small stuff! Have you ever wasted an entire evening by worrying about something you're supposed to be doing? Was it worth it? Instead of agonizing and procrastinating, just do it. If a project seems daunting and you find yourself avoiding it, try the "Swiss cheese method": break it into smaller tasks and just do one, or set a timer and work on the big task for just 15 minutes. By doing a little at a time, eventually you'll reach a point where you'll want to finish.
Keep things in perspective. Setting goals that are unrealistic sets you up for failure. While it's good to set high goals for yourself to achieve, be sure not to overdo it. Set goals that are challenging yet reachable.
