What goes around, comes around. There is a frame for things coming in and going out of your life. People stay in or disappear from your life. Your commitments change and nothings seems to last forever. However, within all this change you need balance within yourself. There is no excuse for not taking leadership of your direction. The alternative is getting rocked on a stearless boat. No man at the helm taking control. Subjected to outside forces without a rudder. The ability to take control is not unlimited and without restraints but at least puts the balance back. Awareness is the first step to realisation. Be aware of where you are now and where you are heading. Then take small incremental steps. Before you know you are finally moving.
Bottom line: There is no excuse for leadership.
