I dont often like looking behind me. You cant safely drive a car looking only in the rear view mirror right, but when it comes to see how stinking far you have come sometimes it is necessary to glace back.
I love hiking so I will use that analogy- there have been many mountains I have climbed and half way up I think “oh my goodness I have SO far to go!” Then I glace back and think “Holy poop, I have climbed all that way”
So take a brief moment to glace back and pat yourself on the back at the progress you have made and the distance you have traveled. You are not the same person you were last month or last year! Progress has been made and growth has happened!
