My conclusions are drawn from firsthand experience, unlike the scholars who only believe what they read in books written by others. Although I cannot quote from authors in the same way they do, I shall rely on a much worthier thing, actual experience, which is the only thing that could ever have properly guided the men that they learn from. These scholars strut around in a pompous way, without any thoughts of their own, equipped only with the thoughts of others, and they want to stop me from having my own thoughts"
- Leonardo Di Vinci
"I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being is not enough. We must do."- Leonardo di Vinci
One can have no smaller or greater mastery than mastery of oneself.
