Exchange comfort in the present for results that you want in the future.
Working out: Lift the heaviest weights you can handle. Run for as long as you can. Exchange comfort for pain to your body, and eventually you’ll get results.
Working on your craft: Ignore all of the distractions that seem to manifest only before you start to work. Ignore your friends, your family, that pile of dirty laundry. Exchange comfort for pain to your focus, and eventually you’ll get results.
Studying: Admit to yourself that you don’t know enough. Admit that you can learn more than you already know. Exchange comfort for pain to your Ego, and eventually you’ll get results.
