Be Marcus Aurelius.
Become a stoic.
Think more of virtue than of success. Success is a hollow word, like in nutrition “it’s an empty calorie”. Rather focus on the virtues of your life. Those are life-giving, filled with “soul nutrients”.
So ... dammit man:
Feed the cat.
Take the dog for a walk.
If that’s all you do today, you made it.
Help a struggling neighbour make that rent payment just this month - do it anonymously. No one needs to know. Certainly not him!
Call your mom.
Tell your Dad you understand.
Call your sister/brother - ask if you can help in any way you can - then help.
Try to read Robert Sapolsky - he says you really don’t have free will - crazy man - it’s rather comforting to forgive yourself thoughtfully. He is a great man actually.
Forgive. Force a smile when thoughts of failure intrude. “Eyebrow” as you pass someone today with a friendly but subtle smile. (You don’t want to be creepy)
Listen to Carl Sagan’s “Pale blue dot” speech. Then watch the Cosmos series - both the new and old ones. See if that makes you feel you’re worrying about the right stuff.
Finally, be like Francisco Goya and “paint” (write software, build a house, make music, write a poem) ONLY for yourself. Begin with the intention that your work will never be allowed to be judged by another. Keep it hidden. Chip at it everyday.
Hit the cool pillow every evening imagining that just ONE more day is good enough for you to fill it up with things like the above. Perhaps even better ones.
