1. I wish I knew that healthy looks different on all different kinds of people. I was a rail growing up, and often times people commented on it saying I was "too skinny". I was not, I was the healthy that God made me at the time.
2. I wish I knew not to worried about what people thought of how I looked but instead work on doing what made me feel healthy and good about myself. Self-explanatory.
3. I wish as a teen I knew how meaningless all the dating-drama was. Looking back I always feel silly about how easily my heart-ached after boys who didn't care about me.

4. I wish I knew how my parents actions (whether it was grounding me or letting me know they didn't approve of certain relationships) were out of love and they never did things just to be mean. It seems so silly now but I remember truly thinking my parents must not love me if they weren't going to let me go to a movie.

5. I wish I knew that the best time to establish a healthy lifestyle is when you are young. Habits are hard to quite and it would have been so much easier if you never started them, establishing a healthy lifestyle as a child or teenager would take so much aggravation away as an adult.
There you go. I am sure there are many more things but those are definitely the first ones that pop to mind and probably the ones that would have made life much more manageable as a teen and again as an adult.
