Taking the first step is dramatic and exciting. Most of us don't remember when we took the first step as a child, learning how to walk, but our parents probably remember it very fondly. But taking the first step is also important in any endeavor, because quite obviously any objective you have in front of you can only be reached if you start. And if you do not start, you don’t even try, you will never reach your goal.
People don’t take the first step because they are afraid of failure, or of the unexpected they will discover. Of what they will learn about themselves on the journey towards the unknown. Even worse, a lot of those people feel completely justified in pointing their finger towards those who do want to experiment, who are dreaming things that are difficult and uncertain and dangerous, and sometimes even impossible, blaming them for daring. Don't be one of those people.
It doesn't matter what you do. It doesn't matter what you aspire to do. Just take the first step.
