Haha, as well they should be!
Honestly though, if it is something that someone really wants to do, they should go for it. It is important, however, to think about exactly why one wants to do it, what they hope to get out of it, and where they hope it will take them.
Unless one has very clear ideas about all of these things, and is very determined, my advice would be avoid.
In any event, it is not something that should be undertaken lightly. Happy to talk further about it though, give advice/my two cents etc.
