When you decide what you want and why you want it, take action immediately. Do not wait for an invitation to act. I promise you, the letter is not in the mail. Know what you want. Know why you want it. Know how you will achieve it. Then get started. Take a class, apply for a job, read a book about it. But do something that moves you forward at a constant pace. If you can walk away for days, weeks, or years at a time, it is not an ambition-it’s a wish. Wishes feel good and rarely come true. Ambition, on the other hand, fuels your days and refuses to be ignored. It challenges your sense of self and fulfills your sense of wonder. So pay attention. And get to work.
