Wanted: Hobby

As my name suggests, I am a curious/eager one.  I have various hobbies because I am just interested in almost everything!  But, my curiosity has its limits.  After being fond of one thing for too long for my liking ("too long for my liking"?  Hmm, that's what she said!), I switch to other hobbies.  Unfortunately, this kind of attitude creates a futile cycle of I wanting and un-wanting certain things.  Perhaps, you can suggest a hobby that will hold my attention span for quite some time?  Or better yet, a hobby that will not fall into that kind of sad, sad cycle?  Any suggestion is appreciated except the inappropriate ones. ;)
