[Kenji]

A stoic does not judge reality like that. He acknowledges that it did not work and moves on. He need not ponder about the fact that it did not work because it cannot be changed and no thinking should be done without a purpose.

Stoic philosophy sounds something like mindfulness or meditation [0], except for the part about "no thinking should be done without a purpose."
