It is never too late to start something you like. As to how long before you can start pointe...It won't happen as quickly as I am sure you would like. Ballet is a lot of work. You really need to get the basics down before advancing to pointe. It will depend on how much work you are willing to put in and how much natural talent you have. I know ballet dancers make it look incredibly easy, but it is hours of hard work and dedication. I am not saying this to discourage you, but so you know gojng in what to expect. Take a beginner class and focus on that. Give it your heart and soul, and then see how you progress. Good luck! I loved dance when I was younger. I hope you enjoy is as much.
