It's a state of mind that anyone can learn to adopt. Your thoughts are your world, make them grand and change them if they do not serve you. Don't live in your own past. Inspiration is the fuel that will get you to your destination. No fuel, no journey.
Books inspire, so read.
Listen to motivational tapes. Talk to people you find inspiring. We all need to work hard but we also need to play hard and rest hard. Reaching your goal should not be at the cost of everything else in your life. Along the path take time out to help others.
