Courage to say No
It takes courage to say yes to all that grows your dreams and no to what doesn't.
Someone said "No" to me recently, I approached them to partner with me on a project and they delined to. You see the project is my dream, not theirs, you need to find those that are aligned with your dreams so they don't pull you away from the path. If someone said no to you, they have done you a favor by letting you know that your path is not theirs. Just work harder to find the right partners and you will, it might take a little time.
It's okay to say no to others, be passionate about your goals, be obsessed about reaching your destination. Keep your eyes on the ball and be alert to weed out all that will detract you.
