Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it.
Steve Jobs
You've got to eat while you dream. You've got to deliver on short-range commitments, while you develop a long-range strategy and vision and implement it. The success of doing both. Walking and chewing gum if you will. Getting it done in the short-range, and delivering a long-range plan, and executing on that.
