The person staring at the rearview mirror eventually crashes into something ahead.

Attention has to be somewhere, and if it is behind you, it is not on what is coming. Reviewing the past feels responsible, like you are learning from it, but past a point it is simply not looking where you are going, and something ahead eventually collects the bill.

Give the past a defined amount of your attention rather than an open-ended amount. Take the lesson and turn forward. What is ahead is the only part you can still influence.
