You can never know the future; you do the best you can in the present by learning from the past.
Don't cry over the past, its gone. Don't stress over the future, it hasn't arrived. Live in the present and make it beautiful.
If the PAST calls. Let it go to voice-mail, it has nothing new to say.
Tomorrow is not promised and the past cannot be changed therefore live each day to the fullest and know that every new day is a blessing.
To grow, you must be willing to let your present and future be totally unlike your past. Your history is not your destiny.
