I agree that one should try to be "replaceable." As Jeff M pointed out, being replaceable means taking a vacation in peace, enjoying time with your friends and family in peace. The people who try to be "irreplaceable" are only hurting themselves, both in their personal and professional lives.

One of the ways to work towards being replaceable is to document *everything*, document thoroughly, and make sure others know where to find this documentation (in the filing cabinet in the basement bathroom with the "beware of tiger" sign on the wall :hehe:)
