Life is not so much like an excel document

If my life was an excel document, I would be all set. The two things that I am actually sure of and somewhat confident in have been created in excel documents...one being my work schedule, the other being my finances.  Yet, life is not an excel document were I can just plug in numbers, names, and dates, it is a crazy uncontrollable cluster of things that come up without warning.  But we can all learn something from an excel document, everything has a place whether it be in A1 or Z16 we can find a place to put it, and if not, we can put it in the recycling bin...
