By nature we are a very self centered people. Through following Christ we learn to die to our desires that might conflict with God. We must decrease that He might increase. That doesn't mean we give up being who we are. If anything we become more who we are truly in Christ. We learn to accept ourselves. Give of ourself to others and learn to receive. Which sometimes can be the hardest of things to do.
The more we know Gods love for us the more we want to please God rather than wanting the approval of man. We learn to say no. We learn to take care of ourselves. Not in a selfish way but in a Godly way. We cannot care for others if we don't care for ourselves.
One of the most important things we can do is allow ourselves time to be alone with God. To meditate. Maybe journal. Fast Pray. What God puts on our heart to be with Him. Maybe it is just to be still and listen for the quiet or that still small voice.
