18. My child, learn to value Wisdom while you are young, and you will still be able to find her when you grow old.
19. Work as hard to find Wisdom as a farmer works to plough and sow his fields; then you can expect a good harvest. You will have to work at it for a while, but you will soon be enjoying what you have earned.
20. Undisciplined people find Wisdom's demands too hard and don't have enough determination to meet them.
21. Her requirements are a burden heavier than they are willing to bear, and they quickly lay them aside.
