Being smart is good, being patient is better

"I can think. I can wait. I can fast."

"That's everything?"

"I believe, that's everything!"

"And what's the use of that? For example, the fasting-- what is it
good for?"

"It is very good, sir. When a person has nothing to eat, fasting is the
smartest thing he could do. When, for example, Siddhartha hadn't
learned to fast, he would have to accept any kind of service before this
day is up, whether it may be with you or wherever, because hunger would
force him to do so. But like this, Siddhartha can wait calmly, he knows
no impatience, he knows no emergency, for a long time he can allow
hunger to besiege him and can laugh about it. This, sir, is what
fasting is good for."
