Marc Andreessen, co-founder of Netscape and Andreessen Horowitz, on driven people:

I define drive as self-motivation—people who will walk right through brick walls, on their own power, without having to be asked, to achieve whatever goal is in front of them. 

People with drive push and push and push and push and push until they succeed. 

Winston Churchill after the evacuation of Dunkirk:

“We shall not flag or fail. We shall go on to the end, we shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air, we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.”

Winston Churchill
