People never appreciate what they have until it's gone

Whenever a relationship or opportunity comes to an end, there is always difficult times of mourning and sad feelings associated with it. Respect that. Remember that every end entails a beginning of something new. Everything that should eventually end – ends, and you must be happy with it. Moreover, every time it happens you probably realize this fact at heart. But what can actually change your life is your ability to take time to invest in your future instead of dwelling on the past.
