I sort of cycle through and meditate on the below quotes a few times a week.
"Humanity has no forgotten how infinitesimal, how impermanent and how ignorant it actually is. Ptolemy has been ridiculed for conceiving the earth to be the center of the universe, yet modern civilization is apparently founded upon the hypothesis that the planet Earth is the most permanent and important of all the heavenly spheres. Ignorant of the cause of life, ignorant of the purpose of life, ignorant of what lies beyond death, we devote the precious span of our earthly years to the futile effort of establishing ourselves as an enduring power in a realm of un enduring things."

“It is not necessary for a man to be actively bad in order to make a failure in life; simple inaction will accomplish it. Nature has everywhere written her protest against idleness; everything which ceases to struggle toward an ideal, the constant effort to get higher and further, which develops manhood and character.”
― James Terry White
"How we spend our days is how we spend our lives"
“Concentrate every minute like a Roman— like a man— on doing what's in front of you with precise and genuine seriousness, tenderly, willingly, with justice. And on freeing yourself from all other distractions."
- Marcus Aurelius
Discipline = freedom
