The worst a man can go through - the ongoing failure to recognise that the only value that matters is the value which he attaches to himself by himself. All other estimates of his value are irrelevant and indifferent.
Whatever you do some will approve and others disapprove - so work from a position of freedom.
When you look at those whose approval we are inclined to seek - they are the degenerates whose approval or disapproval is of no value. The only approval a man needs to seek is his own.
As Epictetus said - you want a witness, be your own.
