"The tyranny of fortune" - Descartes, sounding like Epictetus

As pointed out by Robert Dobbin, in his introduction to The Discourses and Selected Writings.

Rene Descartes:

I undertook to conquer myself rather than fortune, and to alter my desires rather than change the order of the world, and to accustom myself to believe that nothing is entirely in our power except our own thoughts...Here, I think, is the secret of those ancient philosophers who were able to free themselves from the tyranny of fortune, or, despite suffering and poverty, to rival the gods in happiness.
