Shampoo and condition your hair as you normally would, rinse your hair thoroughly, then blow dry it or let it air-dry. Avoid adding any styling products, since you want your hair to be squeaky clean without anything coating the hair shaft. Chalk adheres best to "naked" hair. The oils and waxes from styling products will create a barrier between your hair and the chalk, which affects the vibrancy of your results. Put on an old T-shirt and cover your work surface with a towel before you start working with the chalk. This dip-dyed look typically lasts 1 day and will probably fade a little as the day progresses, especially if you're spending time outside. The chalk should easily wash out of your hair with water and a little shampoo later that evening. If you have platinum blonde hair, it may take 2-4 shampoos to completely remove the color. Since chalk tends to dry out hair, follow up with a deep conditioner or hair mask to restore some of your hair's moisture and shine.

Not getting enough sleep can affect your concentration and cause memory problems, hindering your learning process. A healthy sleep schedule should be kept up as lost sleep has a cumulative effect on your mind and body. As a general rule, the required amount of sleep for optimal functioning is: 9-11 hours a day for children 8.5-9.5 hours a day for teenagers 7-9 hours a day for adults As a general rule, eating healthy will improve your overall well-being, both mentally and physically. Improve your capacity to learn by consuming healthy, "smart" foods that aid with concentration. Make sure to eat a well-balanced breakfast every day, avoid high fat foods, and try to add learning-friendly foods to your diet, such as: Omega 3-rich fish (e.g. salmon) Whole grains Avocados Blueberries Dark chocolate Regular exercise is a key component to concentration and learning potential. If possible, exercise right before studying, which will raise your focus for 2-3 hours. If your concentration starts to fade while reading or studying, take a 15 minute exercise break to renew your energy (e.g. a quick walk around the block). Exercise also releases endorphins and serotonin, which boost mood and fight depression. You don't have to bust out the weights or sports equipment. A brisk walk or jog around the block will do. Get the best learning experience possible by keeping an open line of communication with your teachers. Ask questions at appropriate times (e.g. after class), visit during office hours, and follow-up by email to confirm that you have absorbed what they told you. Reaching out will let a teacher know that you appreciate their time and wisdom, and that you should be taken seriously. Setting clear goals for your learning process will keep you motivated and organized. Be realistic about your goals in terms of time and complexity. For example, if you want to learn the theoretical component of how to drive, aim to read and retain one chapter of the driving manual per week.

Get a 2-gallon (7.6 l) bucket and fill it up with water. While you can use warm water, cool water will work well in most circumstances. This water will be used to help clean excess grout off the tile. If you'll be grouting a large wall area, you may want to fill two buckets up. Wait about 20 to 30 minutes after you first applied the grout. Then, use your sponge to wipe the tile back and forth. Focus on the surface of the tile, not the joints. After you've cleaned a small section, dunk your sponge in the clean water. Use a clean part of the sponge for each wipe. When the sponge gets covered in grout, clean it in your bucket of water. Repeat sponging every section until only a thin layer (or "haze") of excess grout remains. Use a hydrophilic sponge, if you have one. You can purchase one at a home improvement store. Clean your sponge, then slightly depress the sponge with a finger and run that part of the sponge over the joints. Avoid pressing too hard, as you don't want to remove too much grout. When doing this, focus on making sure the grout lines are uniformly shaped and have the same depth. Wait until the grout is completely dry. This could take about 30 minutes. Then, take a microfiber towel and buff the surface of the tile. To buff, use a moderate amount of force to rub the cloth in a circular fashion on the tile. Rotate the cloth so can use a clean part on each tile. When your cloth is covered with grout, use a new one. Avoid using a cotton towel or anything abrasive. You could scratch soft tiles. After you've grouted interior joints, you'll need to apply caulk to joints between tile and other surfaces like bathtubs and sinks. This is important, as grouting exterior joints could cause cracking. Choose a caulk that matches the color of your grout. Then, apply a minimal amount to fill the space. Take a slightly rounded surface, like the back of a toothbrush, and lightly run it over the caulking. When doing this, you should compress it into the joint and create a uniform appearance. When you're done, take a wet microfiber cloth and wipe off extra caulk.

If you dislike olive oilor simply don't have any on handsubstitute the same amount of another vegetable oil, such as coconut oil. This won't change the flavor of the roasted Brussels sprouts, and will prevent them from sticking to the pan just as well as olive oil. Coconut oil may slightly alter the flavor of the sprouts. It may give them a very mild coconut taste, and will also make the sprouts taste sweeter. Other types of vegetable oil you could use include safflower oil, sunflower oil, peanut oil, or sesame oil. If you're in a rush when preparing baked Brussels sprouts, you can save time by cutting the sprouts in half before mixing them with the olive oil and salt. Then, instead of roasting the sprouts for 40-45 minutes, roast them for 20-23 minutes. Keep the oven at 400F (204C); you don't need to alter the baking temperature. Use a sharp knife to cut the frozen Brussels sprouts. They'll be a little tougher to cut than thawed sprouts, but can be cut in half relatively easily. If you'd like your roasted Brussel sprouts to have more flavor, add tangy, sweet balsamic vinegar before drizzling the mixture over the frozen sprouts. Mix 3 tablespoons (44mL) of balsamic vinegar with 12 cup (120mL) of olive oil before pouring the mixture over the top of the sprouts. Once they're mixed, pour the vinegar and oil over the sprouts and add salt. You can purchase balsamic vinegar at any grocery store or supermarket.
