I look at it this way, life is too short to not go after ones dreams, desires or whatever you may call it. You don't want to be on your death bed wondering about all the things that could of been. You don't want to go through life full of regrets. Where there's a will there's a way. I believe you should pursue your dream of being a nurse. 35 or 85. You only have one life to live. Live life to the fullest. Go after what you really want. Don't let anyone discourage you.
