“True independence and freedom can only exist in doing what’s right”

This quote is saying that the freedom and independence you have is based on you doing what is right. If you do something right on your own then that’s having freedom because you know what you are doing and what is right and what is wrong. If you believe that you can be independent and you deserve freedom then you should know you limits. For example, if you are already old enough to go out with your  friends, and you just leave the house without having to tell your parents that you're going out you should still tell you parents. You have to know what is right and you won’t have to worry about them being worried about where you are or who you are with. You also have to be in charge of what you are going to be doing or who you are going to be with. If you don’t know if what you're going to do is going to turn out well then you should just leave it for another day. Even though you have freedom and you are all on your own you should still be watching what you are doing because you never know what could happen or where you will end up. If you do what is right and choosing the right choices then you are responsible for your own self.
