What do I have to go through to become an RN (Registered Nurse)?

I'm in high school and my plan is to become an RN. Can someone tell me what I will have o go through to do so, or what you had to. I would like to know what i will have to go through with schooling and with the experience I will need to become an RN as my profession. If you have experiences from being an RN, I would love to hear about them to help me know this is what I want to do.
