It is only when you are asked to believe in Reason coming from non-reason that you must cry Halt. Human minds. They do not come from nowhere.
— C. S. Lewis

Don't halt before you are lame.
English Proverbs halts quote

Quit thinking that you must halt before the barrier of inner negativity. You need not. You can crash through... whatever we see a negative state, that is where we can destroy it.
— Vernon Howard

You're confronted with the quandary: do I grind things to a halt? Ideally you would, but I have better things to do than educate people.
— Wentworth Miller

Let your actions always speak for you, but be forever on guard against the terrible traps of false pride and conceit that can halt your progress. The next time you are tempted to boast, just place your fist in a full pail of water, and when you remove it, the hole remaining will give you a correct measure of your importance.
— halts quotation by Og Mandino
