seeking wisdom

I broke up a fortune cookie some point during the last week that held the proverb “You’ll accomplish more later if you take some time for yourself.”
How do you decide which things you let go?
Vanessa and I had similar discussions this week and through all of that, I’m still left with the question, how do you decide such a priority?
How selfless are we called to be?
How much are we to empty ourselves from our thinking and do the good work we feel called to do?
How much, and to what degree, do we stop ourselves from doing that work and pursue other things, which are also good?

My son, forget not my teaching, keep in mind my commands;
For many days, and years of life, and peace, will they bring you.
Let not kindness and fidelity leave you; bind them around your neck;
Then will you win favor and good esteem before God and man.
Trust in the LORD with all your heart, on your own intelligence rely not;
In all your ways be mindful of him, and he will make straight your paths.
Be not wise in your own eyes, fear the LORD and turn away from evil;
This will mean health for your flesh and vigor for your bones.
Honor the LORD with your wealth, with first fruits of all your produce;
Then will your barns be filled with grain, with new wine your vats will overflow.
The discipline of the LORD, my son, disdain not; spurn not his reproof;
For whom the LORD loves he reproves, and he chastises the son he favors.
Happy the man who finds wisdom, the man who gains understanding!
For her profit is better than profit in silver, and better than gold is her revenue;
She is more precious than corals, and none of your choice possessions can compare with her.
Long life is in her right hand, in her left are riches and honor;
Her ways are pleasant ways, and all her paths are peace;
She is a tree of life to those who grasp her, and he is happy who holds her fast.
The LORD by wisdom founded the earth, established the heavens by understanding;
By his knowledge the depths break open, and the clouds drop down dew.
