I echo those sentiments
Just do it!
Fortunately for me I have always and still remain to pursue those ambitious dreams and goals that my heart desire. The one thing that I have learned over the years is that, you dont know the result of your pursuit, but regardless of the result it is the journey that makes it beautiful. One of my greatest fear is swallowing the bitter taste of regret, while saying I wish I would have. The only key that opens the door of changing the future is present.
