Concision in style, precision in thought, decision in life.
Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.
When something is a vocation, you don’t really make a decision about it.
The sole ultimate factor in human decisions is physical force. This we must learn, however repugnant the idea may seem, if we are to protect ourselves and our institutions. Reliance on anything else is fallacious and ruinous.
The only person you are destined to become is the person you decide to be.
The most difficult thing is the decision to act, the rest is merely tenacity.
Never tell your resolution beforehand.
Indecision and reveries are the anesthetics of constructive action.
If you cry “Forward,” you must without fail explain in which direction one must go.[Если Вы зовете вперед, то непременно указывайте направление, куда именно вперед. ]

I am not a product of my circumstances. I am a product of my decisions.
Every man gotta right to decide his own destiny.
