"Every action needs to be prompted by..." - Quote by Leonardo Da Vinci

“In whatever system where the weight attached to the wheel should be the cause of motion of the wheel, without any doubt the center of the gravity of the weight will stop beneath the center of its axle. No instrument devised by human ingenuity, which turns with its wheel, can remedy this effect. Oh, speculators about perpetual motion, how many vain chimeras have you created in the like quest. Go and take you place with the seekers after gold.”

“A luminous body will appear more brilliant in proportion as it is surrounded by deeper shadow.”

“It reflects no great honor on a painter to be able to execute only one thing well -- such as a head, an academy figure, or draperies, animals, landscapes, or the like -- in other words, confining himself to some particular object of study. This is so because there is scarcely a person so devoid of genius as to fail of success if he applies himself earnestly to one branch of study and practices it continually.”

“Courage is like love; it must have hope for nourishment.”

“The craving for equality can express itself either as a desire to pull everyone down to our own level (by belittling them, excluding them, tripping them up) or as a desire to raise ourselves up along with everyone else (by acknowledging them, helping them, and rejoicing in their success).”

“At times one remains faithful to a cause only because its opponents do not cease to be insipid.”

“Don’t indulge in any unnecessary, sophisticated moves”

“[W]hat counts is that one perceives excellence and dares to give it expression, which sounds little but is in fact a great deal.”

“When you become comfortable with uncertainty, infinite possibilities open up in your life. It means fear is no longer a dominant factor in what you do and no longer prevents you from taking action to initiate change. The Roman philosopher Tacitus rightly observed that 'the desire for safety stands against every great and noble enterprise.' If uncertainty is unacceptable to you, it turns into fear. If it is perfectly acceptable, it turns into aliveness, alertness and creativity.”
