That is a sign we have all seen at a place where we wanted to park. It can be frustrating to see that at times.
I think that there are certain places in life, where we sometimes really want to "park" but we should not if we want to do great and remarkable things. One of the areas where we should not park is beside your past/mistakes.
13 Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, 14 I press toward the goal for the prize of the upward call of God in Christ Jesus. - Philippians 3:13-14
All of us have made mistakes in the past, we are humans and that is expected but we make an even bigger mistake when we dwell on the past and especially when we dwell on the mistakes in the past. It is vital for us to forget those things that are behind us and press on to what God has in store for us!
This is especially true for leaders.
What are your thoughts on this? What do you do to forget the past and press on?
