In order to move on from day to day we must be willing to do just that, move on from the days past and look towards our future. Today may not be your brightest day, and surely every day will not be. As long as one is able to forget about the bad days of the past and look forward to the bright days of the future then one will be able to overcome just about anything that life throws at them.
We must realize that life is full of its bright spots, while having its dark and gloomy ones as well. Not everything that you plan out will happen according to plan, and not everything that you want to receive will be something that you actually receive. Remember to keep pushing, when it seems as though nothing in your life is right, keep pushing, keep hoping, keep turning the pages and starting brand new days, for soon your sadness will be overcome with joy, and the feelings of pain you endured will be overcome with pleasantness.
