Happiness
In poker they call this “Happiness Expected Value”. The difference in happiness between winning 1mil vs 100mil is less than the difference between winning 1mil and getting nothing. Therefor from a happiness standpoint it is correct to take the 1mil for most people.
One key to maximizing profits is to ensure happiness EV aligns with $EV as much as possible. For example, playing within your bankroll and comfort zone allows you to make correct plays, be they big blufffs or speculative calls. Otherwise you can end up sacrificing $ in an effort to avoid the suffering of negative variance beyond your tolerance.
Then again, I’m a nit...
