Whatever you can do, or dream you can, Begin it. Boldness has Genius, Power, and Magic in it. Begin it Now! (Goethe)

I do not think that there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... Such emotions make a man forget food, sleep, friends, love, everything. (Nikola Tesla)
"Nothing can stop the man 
with the right mental attitude 
from achieving his goal; 

nothing on earth 
can help the man 
with the wrong mental attitude."

Thomas Jefferson
