3 bricklayers are asked "What are you doing?" The first says "Laying bricks." The second says "Making $9.30 per hour." The third says "I'm building the world's greatest cathedral."
Your mindset determines your actions. Know what you are doing is important and makes an impact. The impact might be down the road, maybe to someone else indirectly, or it could be important to yourself to get you closer to the next great thing.
In everything you do, know that it is important and worth doing and to the best of your ability.
