[Quiet Man Cometh]

Saying what I actually meant to say, you don't need to commit to anything, really, just try it out. For example, if you want to see about being a children's librarian, see if your local library has any children's activities that you could volunteer for. That's what I did at my local library when I was looking into volunteer work. A youth educator, I am not, but I can handle low-level 'minding' for brief periods of time.
