Article in English: If you have a long night of studying ahead of you, make a plan for the day. Aim to work for 30-60 minute periods with 5-10 minute breaks in between. Your brain needs the break to recharge. It's not laziness – it's letting your brain synthesize the information. Try to switch subjects every hour or so, too, to prevent yourself from getting bored and saturating your mind. Too much of one subject and your brain will start going on autopilot. A new subject will wake up your mind and your motivation. Sometimes it's hard to study because the real world keeps creeping into our minds, good or bad. We feel like we don't have control over our thoughts, but we do. Tell yourself that you'll think about that problem or that girl or boy when you're finished. You'll feel a bit of solace knowing you'll get to it eventually. And when the time comes, the urge may have actually passed.  If you start to feel your mind wander, stop it dead in its tracks. Take a second to shake it off, and then resume with the material. You are the ringleader of your thoughts. You started them, and you can stop them, too! Keep pen and paper besides you and write down everything that comes to your mind during your study sessions. Do or think about those things once you're having a pause. Let's say you just got done reading 20 pages of a textbook. The last thing you should do is jump into is 20 pages of the next textbook. Instead, do a quiz with some flashcards. Make a few charts to help you remember those economics stats. Listen to those French tapes. Do some studying that involves different skills and different sections of your brain. Point blank, you'll be less bored. And it'll be easier for your brain to process, too. Switching up what skills you're using helps you brain process the information faster and hold onto it. The time will go faster and you'll remember it better? Check and check. Sometimes we need a little pick-me-up to keep ourselves going. If the good grades aren't enough of a reward, create something else to keep you concentrated on...
