Philippians 3.

Paul says to the Philippians in this chapter to model their lives after his. Just before that, he offered this thought that they (and we) could model:

12 I don’t mean to say that I have already achieved these things or that I have already reached perfection. But I press on to possess that perfection for which Christ Jesus first possessed me. 13 No, dear brothers and sisters, I have not achieved it, but I focus on this one thing: Forgetting the past and looking forward to what lies ahead, 14 I press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us.

Philippians 3:12-14 New Living Translation

Forgetting the past and looking forward — this is something good to do.
