As if all was safe and well with you, you have dwelt upon the final area of study, which has to do with unchangeability, so that you can make yourself unchangeable—in what? Your cowardice, means-spiritedness, admiration for the rich, your failure to achieve what you desire, and your lack of success in avoiding what you want to avoid. These are the things that you have been laboring to secure.

~ Epictetus
