Letters from a Stoic - Lucius Annaeus Seneca - Bog

I feel, my dear Lucilius, that I am being not only reformed, but transformed. I do not yet, however, assure myself, or indulge the hope, that there are no elements left in me which need to be changed. Of course there are many that should be made more compact, or made thinner, or be brought into greater prominence. And indeed this very fact is proof that my spirit is altered into something better, - that it can see its own faults, of which it was previously ignorant. In certain cases sick men are congratulated because they themselves have perceived that they are sick.
