Thoughts are things; they have tremendous power. Thoughts of doubt and fear are pathways to failure. When you conquer negative attitudes of doubt and fear you conquer failure. Thoughts crystallize into habit and habit solidifies into circumstances. – Bryan Adams
When you are in any contest, you should work as if there were – to the very last minute – a chance to lose it. This is battle, this is politics, this is anything. – Dwight D. Eisenhower
