Always remember, you may not be able to reach what's in front of you, until you let go of what's behind you.
i'm glad you said MAY not rather than WILL not, because some things should NOT be forgotten. we build our futures upon our pasts to a large extent, from getting jobs based on our work experience to responding to situations based on our life experience. harping on the past is harmful but forgetting it entirely is no better.
