You are so made that you can only carry the weight of twenty-four hours, no more. If you weigh yourself down with the years behind and the days ahead, your back breaks. God has promised to help you with the burdens of the day only. If you are foolish enough to gather again that burden of the past and carry it, then indeed you cannot expect God to help you bear it. So forget that which lies behind you and breathe in the blessing of each new day.
