This quote is a cute light one that might be a good for you to remember when you to start to grow and change yourself.
Know there will be people in your life that won't want you to change - they will fight you trying to change yourself, especially the people closest to you. When you change it will make them have to change as well, at least somewhat, because they will have to be dealing with a new person. A lot of people are uncomfortable with change so they resist it in themselves and they will resist it in you.
Remember don't let anyone tell you not to grow and find your self. If they make fun of you think of this:
Remember every oak tree started out as a couple of nuts who stood their ground.
Just try to learn and grow in a positive way. It will be a journey filled with all sorts of emotions and trials and tribulations.
You can do it.
