Pleasing vs. Necessary?

Many of us at least to some degree have errors in our thinking about what pleases God.  I am assuming this based on the conversations I have had with a lot of folks and the thoughts I have on a regular basis.  We tend to think of certain things that we do as spiritual and directly for God, while other things we view as waste or only 'the necessary.'  We struggle with guilt over time wasted in the necessary things (going to work, cleaning the house, eating lunch, etc.),  while we spend so little time doing the truly spiritual things (going to church, going to Bible studies, sharing our faith, going on missions work, etc.).  Do you feel like that sometimes?  I do, and a whole lot of other christians I have talked to do.  So here we are we think, stuck with so much time that must be spent doing the necessary things, and so little time to do the really spiritual things.  There are a lot of reasons why we think like this, but the fact is that line of thinking is faulty.  If taken out of context, this next line could be harmful, but it's the truth.  Teaching a history class is no less spiritual and pleasing to God than missionary work in China.  Both can either be pleasing or displeasing to Him.  The question is motivation.  Here I will let a wiser man explain 

"The Lord Jesus Christ Himself is our perfect example, and He knew no divided life.  In the Presence of His Father He lived on earth without strain from babyhood to His death on the cross.  God accepted the offering of His total life, and made no distinction between act and act.  "I do always the things that please him," was His brief summary of His own life as it related to the Father (John 8:29).  As He moved among men He was poised and restful.  What pressure and suffering He endured grew out of His position as the world's sin bearer; they were never the result of moral uncertainty or spiritual maladjustment."  (The Sacrament of Living in The Pursuit of God, by A.W.
