Train yourself to crave your goals. Understand luck, and make it work for you. Marathon runners keep going not by focusing on the whole course, but on the next drink station, the bottom of the hill, and when the pain comes, the next lamp post. The plans we make to achieve our dreams are the blueprints for success. A written plan focuses the mind on goals.
Intermediate steps move one step by step closer to success.
Goal setting must be an ongoing process. Goals that are no longer meaningful must be replaced by ones that are. A journey of a thousand miles starts with a single step. I really like that one. I repeat it so often.
