Braces

So I’m in high school, about to be 16 and all my life I’ve had messed up teeth, a gap, various missing teeth etc. the dentists never worried about braces because they thought my teeth would form on their own. Well... tomorrow I’m getting braces, and I’ve been preparing myself through YouTube and articles. Is it bad that I’m finally happy to fix my smile and be confident with it? And I’m actually excited to get braces? Also YouTube and articles can only tell you so much so is there any tips or tricks that I can take with me? (I only need to have the braces for 14 months maximum :)) (I know this doesn’t technically fit the make up category)
