Starting is the first step to becoming the new you. If there is something you would like to become then you must start with taking action. If there is a skill you want to learn you must practice that skill. If it’s knowledge you want to learn you must seek where to find it.
Stopping is also the first step to becoming the next you because to start something new you also must stop something old. The birth of something is always the death of something. There are two sides to everything.
Become mindful and aware of when something ends then something new begins. There is a beginning, middle and end. To become The New You you must end the Old You.

Why wait till something ends? Better to end it intentionally, and replace it intentionally with something you prefer yourself to become. There are things one cannot change, but there are things we can change. Our personslities, in particular. Don’t like something about your personality? Change it. If you don’t like it, chances are no one else does either. Be intentional. The world can never have enough nice people. (I’m assuming no one really wants to be an asshole. Assholes are not nice people!)
