A lot of it is forgetting the sinful nature that we still have, and having the Holy Spirit and Christ living in us also.  It comes down to this: who are you trying to please?  Yourself, others, or God.  Our objective should be God first.  We all struggle with this, even Paul the Apostle struggled with it.  It is a matter of a daily and moment by moment decision of who you are pleasing:  yourself or God.  So essentially, as Paul describes it, we all have a battle of who is getting control of us:  ourselves or God.  God can have control if you let Him.
