Salary, grades, number of vacations or downloads: whatever metric you use to keep track of your life is something that will normalize meaning you will get used to it. That doesn’t mean that you should never track your success with numbers. It does mean however that while number goals can motivate us we need other things to make us happy. Quantity normalizes but quality does not. You easily get used to achieving A grades and even expect that from yourself and be disappointed by anything less. But if your skill level and the challenge grow in relation to each other the work you put into worthwhile projects will not normalize but can be a source of a more quiet and content happiness.
