Set aside a few minutes every day to think about how you learn. Ask yourself, "Do I understand more with notes or highlighting?" Write down a list of what you consider to be your strengths and weaknesses when learning something new. For example, do you quit easily when you are frustrated? Don't wait until the formal exam date to see how you perform under pressure. Set up rounds of practice testing well beforehand. Give yourself a prep exam or ask a friend to give you a pop quiz. If you use flashcards, do not remove cards as you feel comfortable with them. It is best to keep all cards in play and to practice frequently until the date of an exam. Brains can get lazy, especially when they are good at certain tasks. Once you reach mastery at a certain task, you need to move on to a new one. For example, if you can easily play poker, push yourself to learn blackjack. You want your mind to be constantly challenged. Set a high bar for new learning tasks. Try to make a difficult recipe or change your own oil. Keep it challenging, but not impossible. This will help you to remember how to learn quickly by improving how your mind performs under stress. For maximum benefit, try setting aside your technology, such as the spell checker on computers, and going manual for a bit. Playing fast-paced action video games creates a high level of difficulty that pushes users to adapt to new physical skills. This can result in gamers having an advantage when learning to ride a bike, for example. Before you start a task, ask yourself, "Why am I doing this?" The more passionate that you are about a task, the better. Your excitement will let your brain know that it is time to learn. Focus all of your attention on one task before moving on to another. Finish your game of chess before moving on to checkers. If you switch actions mid-stream you lose valuable time. You also have to get your mind 'back in the game' every time you switch jobs. The exception is if you are completely stuck on a task. If so, leave that math problem behind and work on writing for a bit before coming back to it.

Q: Choose plastic bags designed specifically for transporting fishthey should have flat bottoms when filled and be at least 3 mils thick (and ideally 4 or more mils). Likewise, use fish shipping containers that have sturdy cardboard outer boxes and inner Styrofoam boxes that fit inside perfectly. You can order these online from companies that deal in exotic fish supplies. You might also find them in fish supply or pet stores. The bags and boxes come in various sizes. If you're putting a single fish in each bagwhich is the safest methodchoose bags that are about 3 times as wide as your fish breed's average length. Choose the box size based on the number of bags you intend to ship at a time. Your chosen shipper might not absolutely require fish-specific bags and boxes, but they're your best bet for getting your fish to their destination. Move the fish you intend to ship to a separate tank that's set at their ideal water temperature. Use an aerator and filter to keep the water clean, oxygen-rich, and conditioned properly based on the fish breed's needs. Do not feed the fish while they're in isolation. You want them to create as little waste as possible during their journey. Check for any signs of disease during this time, since you don't want to ship out diseased fishespecially to a paying customer. During the 24-48 hour isolation period, incrementally reduce the water temperature from the ideal to the lower healthy limit for that fish breed. Turn down the tank's heater a little more every few hours and check the progress with a tank thermometer. This process will slow their metabolism, which means they'll consume less oxygen and produce less carbon dioxide and waste. You might think you should increase the temperature to make up for heat loss during shipping, but the box's insulationalong with heating pads, if neededwill take care of that.
A: Buy shipping bags and boxes designed for fish transport. Place your fish in an isolation tank for 24-48 hours without feeding them. Decrease the water temperature gradually to your fish breed's lower limit.
