If I were to condense this statement, I would say: Focus on the good, learn from the bad and keep trying. And the thing about cameras is: unless you play with the image you get the unvarnished truth.
Paul, the apostle puts it this way...
Philippians, Chapter 3 (WEB)
7 However, what things were gain to me, these have I counted loss for Christ.
8 Yes most certainly, and I count all things to be loss for the excellency of the knowledge of Christ Jesus, my Lord, for whom I suffered the loss of all things, and count them nothing but refuse, that I may gain Christ
9 and be found in him, not having a righteousness of my own, that which is of the law, but that which is through faith in Christ, the righteousness which is from God by faith;
10 that I may know him, and the power of his resurrection, and the fellowship of his sufferings, becoming conformed to his death;
11 if by any means I may attain to the resurrection from the dead.
12 Not that I have already obtained, or am already made perfect; but I press on, if it is so that I may take hold of that for which also I was taken hold of by Christ Jesus.
13 Brothers, I don’t regard myself as yet having taken hold, but one thing I do. Forgetting the things which are behind, and stretching forward to the things which are before,
14 I press on toward the goal for the prize of the high calling of God in Christ Jesus. (emp. added, GDR)
15 Let us therefore, as many as are perfect, think this way. If in anything you think otherwise, God will also reveal that to you.
16 Nevertheless, to the extent that we have already attained, let us walk by the same rule. Let us be of the same mind.

Christ; better than your past, an example to follow, and the only real future to attain to. Are we focused yet?
