I need to forget whats gone , appreciate what still remains

Starting today, I need to forget whats gone, appreciate what still remains, and look forward to whats coming next. 

Mistakes are of past. We learn by mistakes to correct the future. Hard to seperate future and the past by forgetting.

Always remember your past.. Don't forget it. Because you learn from such mistakes which happened in past,.. It helps you to make your present and future better than past.
