I find it hard to give a useful answer as my comparison is biased by suffering serious depression/anxiety for the last few years. I am happier/less anxious than I have been in the ast due to some combination of medication, therapy and lifestyle changes, but I am still significantly below where I visualise I should be.

You might also be interested in some of the studies described by Daniel Kahneman in thinking fast and thinking slow on how people assess their life satisfaction when framed in certain ways, and the difference between experiencing and remembering self.

I'm usually quite happy, but last years was swamp by unhappiness due to multiple destructive earthquakes hitting my town.
