There are many techniques available to support you with visualization that adds power to your life. Most of them do recommend that visualizing closest in time to the beginning and the end of your day is preferred, for best effectiveness. You can also visualize certain intended outcomes just moments before an event. This is essentially what athletes do, however I am sure that they would also set aside deliberate, alternate times to imagine the successful result for their sporting events.
My favorite daily meditation is watching my mind movie, this is my site about this wonderful visualization tool
