One thing that comes to mind when changing things about ourselves: progress. You see, it's progress the reminds where we started; and it's progress that also shows us just how far we've come.
This is, in no way "patting oneself on the back"; but acknowledging the distance covered from the starting point, until the present day. It's a way to look at what we started with and what we have now; not measured by material things, but by actually looking at our progress. It's a great way to find new hope and overcome frustration. It's also shedding light on solutions and not the problems.
