You will envy other people's hair. Be patient. Embrace YOUR curls. Figuring out how to treat this VERY unique hair type is going to take patience, especially since it has been ignored for so long. Be patient my dear. You'll reach your goals.
Be confident. A lot of people (especially people of your own ethnic group) will say negative things around or about you regarding your natural (see: nappy) hair. You're a pioneer even if you don't want to be. People respond harshly to things they're threatened by or don't understand. Stand up for yourself.
Be adventurous. Try new products. Try to make your own products. Watch a lot of youtube videos and go to hair blogs. Do research. Try new hairstyles.
Be healthy. Take care of your body. Eat well, drink a lot of water, and your hair will grow and love you for it. Don't be bingeing on cheeseburgers and chips and drinking nothing but sodas and expect anything from it. That goes for just general health as well.
