Some things facilitate learning, and other things destroy it. Arrogance destroys it — “I know this already” — have this thought and learning will stop. Also, being tied up in a million things will not help you get to the depth of a thing.
You cannot really change until you get to the depth of something. When learning stops there is no more change, there is no more progress and the soul, whose task it is to learn and change, is bereft.
“This much I have understood, but tomorrow, I will understand even more” — this is a thought of appreciation for what has already been received. It is a good way to ensure that more will be received in the future.
There will always be the opportunity to learn for those who desire it. Learn in such a way so as to absorb the new and live it. That is being sensible, which is the aim of learning.
