True as it's said. And to be honest, this is something we quite often forget. At least I do. At times it can feel as if whatever you're doing got easier. But do know that it is YOU that got better at doing it, and not the "thing" that got easier ;
Great New Year's idea: Start the year with an empty jar and fill it with notes about good things that happen. Then, on New Years Eve, empty it and see what awesome stuff happened that year. Good way to keep things in perspective.
