 I have yet to do the one thing I wish before I die
pj: hmm... you shouldn't because you have expectations?  Do you?  You say, "The thing i want to do"... why do you want to do it?  What do you expect to get out of it.  what is it that you really want?  More knowledge?  more earning potential?  to be around people interested in learning?  Analyze what it really is that you want.  To have fun?
