What are some good hobbies to replace smoking pot that i haven't tried?

I'm working on quitting but i need to fill the time that i used to dedicate to smoking. I'm looking for a job and a girlfriend, which should help a lot. I already exercise and lift weights, snowboard in the winter, write music and surf the internet but these hobbies are not really a replacement for weed, because i did all these hobbies before i quit. I really want to find a unique new hobby, something i haven't heard before and that i can be pionate about. I prefer intellectual hobbies, but outdoor hobbies could be considered. I do live in Colorado, after all.
