Why not? Some things demand a boldness that may not come naturally, that may not fall within our standard modus operandi. There are times in our lives when we need to step out of our comfort zone, to finally be daring and bold!
It is usually when the odds are not in our favor. It is usually when, once in motion, there is no turning back.
But even the likelihood of failure far outweighs living with the nagging wonder of having failed to try. The "what ifs" in life are the hardest pills to swallow.
I have been immersing myself in Ralph Waldo Emerson of late, and I found a quote from his journal that I find unusually stirring. It is this: "Let us answer a book of ink with a book of flesh and blood."
Now I don't presume to necessarily grasp exactly Emerson's meaning from this, nor do I even guess what your interpretation would be. But, to me it is about inspiration. It is about taking our studies, taking the things we have read and then acting upon them with our whole souls, holding nothing back. It is to step forward with boldness and not just live our lives vicariously through book characters or another man's thoughts and dreams. At some point, it becomes our turn to "write our own book", to lay down our own story; to hold nothing back, to not just dream the dreams but be ready to bring them to life.
Perhaps I have come to that point in my life.
Perhaps you have too.
