You drink water when you are thirsty. But the doctors say that you need to drink at least eight glasses of water everyday to stay healthy. Most people ignore the advice and stick to drinking water only when they are thirsty. While they can ignore the advice they can’t avoid the consequences of ignoring that advice.
Drinking eight glasses of water everyday requires going out of the way – meaning you need to drink water even when you are not thirsty. Seems odd to do at first but if you get into a habit, you will get used to it.
Thirst for knowledge works the same way. You can acquire knowledge when you need it (thirsty) or you can develop a habit of acquiring it throughout your lifetime.
The latter is of course the “healthier” choice.
