"Ambition means tying your well-being to what other people say or do. Self-indulgence means tying it to the things that happen to you. Sanity means tying it to your own actions." - Marcus Aurelius
I don't need a promotion to be happy, I do not need a fancy house or the respect of anyone. My well-being is untouched by externals, immune to critique. Today I will do my work assigned without need for encouragement. Without need for a pat on the back or kind words. I will do my best and be happy in that result. If it falls short then I will accept that.
