STOP AND THINK We do not heal the past by dwelling there; we heal the past by living fully in the present. (Marianne Williams, author and lecturer)

Sometimes the failures of the past, or the memories of them, so immobilize us that we cannot function normally. We must overcome that inertia by intentionally working at the present tasks in order to guarantee a better future.
 
Forget the former things; do not dwell on the past. (Isaiah 43:18)
