It helps a little to know that most people are sort of unsatisfied, most of the time.
If you’re doing worse than 7 out of 10 for any length of time, there might be something wrong that needs decisive action. But not being at a permanent 10 doesn’t mean that your life is messed up. 7 is the surprisingly predictable average happiness value for all humans everywhere.
Go ahead and aim for 10, but you’ll be back at 7 before long. Don’t let it ruin your day.
