“The disposition and habits of youth will be very likely to be manifested in mature manhood. You may bend a young tree into almost any shape that you choose, and if it remains and grows as you have bent it, it will be a deformed tree, and will ever tell of the injury and abuse received at your hands. You may, after it has had years of growth, try to straighten the tree, but all efforts will prove unavailing. It will ever be a crooked tree.

This is the case with the minds of youth. They should be carefully and tenderly trained in childhood. They may be trained in the right direction or in the wrong, and in their future lives they will pursue the course in which they were directed in youth. The habits formed in youth will grow with the growth and strengthen with the strength….”
