To wish a life without stairs, without hills and mountains is to wish a dim life without the joy of rising with our own efforts!
Water drops erode mountains not because of their size, but their persistence.
There is no mountain on earth which is greater than the mountain of human madness!
The farthest mountain is the one you think you can never reach and it may even be just by the side of you!
You don't scale a mountain with your mouth, but with your feet.
