I have been in this body for a while but still feel like a kid at heart and that is why I love this quote. I have had many dreams that I did not pursue (too scared) and I still have many dreams. This time, I am catching some dreams---and how do you catch your dreams? Two words---take action. Yes, it is sometimes scary. Yes, you may feel uncomfortable and feel foolish---but that is what life if for---to live your dreams.
Take baby steps or a big leap---it does not matter because you will learn along the way. Don't wait for perfection, do it now and refine it along the way---that way you have no excuses but are living your dream.
