If you're looking to make a career out of tennis instruction, consider becoming a certified professional instructor. Most professional tennis organizations, including the United States Professional Tennis Association (USPTA) and the Professional Tennis Registry (PTR), offer certification programs. These usually involve an application, several workshops, and an exam. These programs generally offer different levels of certification, ranging from basic to advanced. If you want to coach elite athletes, you should opt for a more advanced certification. Being a good tennis instructor goes beyond knowing how to play the game. You also need to know how to communicate effectively with your athletes and successfully teach techniques and skills. Online courses and local coaching workshops can help you hone your coaching skills. To browse different online course options, visit http://coachyouthtennis.com/learncenter.asp?id=178497. If you get certified through a professional organization, they will usually offer additional workshops and courses. If you want to teach tennis in high school or college, it can help to get a degree in an applicable area, like sports science, nutrition and fitness, or physical education. Many of these degrees require internships, which can give you valuable exposure to the world of professional tennis coaching.

Certain hair types and lifestyles mean that you need to wash your hair more. If you have oily skin, thin and fine hair, exercise a lot, or live in a humid area, you probably find that you need to wash your hair often. People with curly, thick hair and normal to dry skin don't have to wash their hair as often. You should keep this in mind when trying to achieve self-cleaning hair. You might have trouble getting your hair to adjust to no shampoo if you have to wash it often. Many people with short hair styles have had success with self-cleaning hair, so if your hair is very long or thick it might be more difficult or you might have a longer adjustment period. Shampoo is a detergent that strips your hair of its natural oils. If you stop washing your hair, it is possible it will adjust and your hair follicles will produce the correct amount of oil to not be greasy. Foaming agents in shampoo can also irritate your scalp and make your hair not as healthy as it can be. Add water to baking soda until it is a slightly gooey texture. The proportions are not an exact science. Instead, just mix the baking soda and water until you like the consistency. Store the mixture in a travel shampoo bottle. Wash your hair with this mixture instead of using shampoo. After you are finished, rinse your hair with 1-2 tablespoons of apple cider vinegar and around 1 cup of water. Pour the vinegar mixture over your head, rub it into your hair, then rinse it out with cold water. Use baking soda and vinegar instead of shampoo for at least two weeks. Thoroughly wash your hair with water every day to remove as much grime as you can. Use warm water at first to remove dirt and oil out of your hair. Finish off by rinsing with cold water to remove any buildup and make your hair shiny. Massage your scalp while you rinse your hair. You will need to use only water to wash your hair for a few weeks. This might be difficult because your hair will get very greasy while it is adjusting. After you get through the weeks of having greasy hair, you can use shampoo alternatives (like baking soda and vinegar) once a week.

Compatibility is incredibly important. That special person may pass every future-spouse test with flying colors, but when you're together, you may find that there's just a lack of...something. Maybe you just don't really "get" each other; maybe you always end up bickering; maybe you just can't talk without running out of things to say after a few minutes. If you're not compatible, you're not compatible, and there's nothing you can do to change that. Sexual attraction is different than compatibility -- it wears off. Compatibility means that your personalities really work well together, and that things just click for you more often than not. Though you may have been wanting to get married for twenty years, you shouldn't start running down the aisle after two weeks with the person you think is Mr. Right. Even if you just have "that feeling," it's very risky to marry someone you've known for just a few months, or even just a year. Give the relationship enough time to know that your feelings aren't just based on attraction, that you can get through some ups and downs together, and that you can really truly see a lifetime of happiness with that person. You may think that you're absolutely sure after just a few months, but this won't give you enough time to test the relationship. You may be absolutely gaga for your special someone, but you need to have the sense that he's feeling it too. Or -- you need to make sure that he's not crazy about you, while you're just feeling "pretty happy." Both of you shouldn't be crazy about each other and completely excited for the rest of your lives together to move on. Though marriage will naturally change two people as they become bonded more closely, make sure that the person you want to be with lets you truly be yourself instead of trying to be some ideal person. If your friends or family tell you you're not being yourself around that person, it's a bad sign. But you will know if you really can't be who you are around that person, because you'll feel yourself holding back. You may love being with that person for a year or two, but you should make sure that you have the same vision of the future -- whether it's settling down in a nice house with two kids, or traveling the world and being nomads together. Though life is unpredictable and neither of you will be able to do exactly what you want, your visions of the future shouldn't be wildly different or you'll run into a lot of trouble. If you've really found your spouse, then you should be able to imagine being with that person for the rest of your life. That is probably a very long time, so make sure that you really mean that you want to see that person grow old, to have kids with that person (if that's what you both want), to support each other's careers or other pursuits, and to truly become life partners. "I do" means "I do want to be with you forever," not "I do want to be with you for a while." If you really cannot imagine the rest of your life without that person, then congratulations -- you have found the right partner or spouse. Now have an incredible journey!
