Tecumseh stated two things that has now been part of my code since I first read about him:
1. "From my tribe I take nothing, I am the maker of my own future"
2. "Live your life that the fear of death can never enter your heart"
Furthermore that has been part of it:
Walt Disney also stated "Keep Moving Forward" which was present in Disney's Meet the Robinsons
A latin poem by Quintus Horatius Flaccus stated " Carpe diem quam minimum credula postero"
In total, live life to the best of your abilities and make it your own.
