Of note is that fact that we wish our family and friends a "happy birthday" when their day comes around.
We don't wish them a "wealthy birthday", a "hit your target birthday", a "beat the competition birthday", a "catch up with all of your emails birthday", an "increase your number of followers birthday", a "reduce your fallow time birthday".
This year, more than most, has proved that life is too short.
If you aren't happy doing what you are doing - do something else.
Happy is enough.
