"On a given day, a given circumstance, you think you have a limit. 

And you then go for this limit and you touch this limit, and you think, 'Okay, this is the limit.'
As soon as you touch this limit, something happens and you suddenly can go a little bit further. 

With your mind power, your determination, your instinct, and the experience as well,
you can fly very high." Ayrton Senna
