"Most people who fail in their dreams fail not from lack of ability but from lack of commitment." ~ Zig Ziglar
Do you always do what you say will do, or say you want to do? Some excuses I've heard: "It's too hard." "I'm not very good at it." "I don't have time."
What keeps you from taking action and fulfilling your desires? Make a list of your dreams and promises. Prioritize and make action steps.
Be persistent in the face of adversity...that's commitment.
