The one bit of advice I would give: Do it while you can. Whatever it is, do it now. Do it while you can. School, dancing, hiking, a trip.........do it now. I did a lot that I am so glad I did not wait to do. Yet I waited on some things I wish I had done, as now I will not do them. You never know when your health will fail or someone else's, when an accident can change your life, when someone will never be there again........anything can happen, anytime,and you are not immune. Do it while you can.
