If you are facing in the right direction, 

all you need to do is keep on walking.

Speed

Speed is useful only if you are running in the right direction.

Think big - John Cleese

Because, as we all know, it’s easier to do trivial things that are urgent than it is to do important things that are not urgent, like thinking. 
And it’s also easier to do little things we know we can do than to start on big things that we’re not so sure about.

quote by John Cleese

Upper and lower ranks - Sun Tzu

Those whose upper and lower ranks have the same idea will be victorious.

quote by Sun Tzu

Vision / action

Vision without action is merely a dream. Action without vision just passes time. Vision with action can change the world.
