I'm 12 and I would really like to learn how to snowboard?

I'm 12 and I love Shaun White! I would really like to learn how to snowboard. My mom has a friend that lives in Colorado and she teaches lessons. She said that I could visit for easter break and I want to, but I don't want to waste my break when I could be doing something else, so I guess what I'm asking is: is it super duper challenging? Am I going to make a fool of myself? Will I waste my vacation? Stuff like that? Do you get what I'm asking? K, thanks!
