I wonder at my own sanity

Another leadership position was offered to me within a group to which I belong.  More of my time is needed to fill this position.  However with this position comes compensation.  Not anything to scream about, but at this point can I really turn down some extra income?  Who needs sleep anyway?!

Really my major concern is that I would be required to attend a three-day conference in Long Beach just two weeks after I have returned from an already two week absences from work.  My clients would not be happy. 

Would someone please draw me a line as to how much is too much to take on?  I am not sure that I know.
