To start anything new is hard. It takes effort to begin to exercise, learn something new or break a bad habit. It requires coordination, planning and collaboration to get a team to take on a new initiative, address a problem, or make changes from preexisting practices.
And that is just it. Once you begin, you create momentum. The obstacles are less frightening and the path forward is clearer . The next day you have something to build upon, and soon enough you are looking back and questioning what was the hesitation in the first place.
Rather than being overwhelmed with the fear of what may be ahead of you, embrace the idea of achieving a milestone by beginning the process. Celebrate Day One, and not just the end, since this was the true achievement, and you did it.
