The definition of proactive is serving to prepare for, intervene in, or control an expected occurrence or situation, a negative or difficult one; anticipatory.
As you go through your day quietly within yourself, observe yourself and take notes. Are you reacting to the situations in your day or, have you taken a proactive stand in your day. If you are like most people, you are reacting to the different event that you are encountering in your day. This means your life could be based off a reactive approach.
To be reactive is to allow situations to dictate to you what your truth is and then you have to come up with a way to manage a situation that you did not plan for or expect. This person is like the ball on the bumper pool table bouncing around from object to object trying to get to a desired outcome. Hoping that if the objects just move out of the way then I would be OK.
The proactive person also has a desire goal or destination in mind. They are aware of the obstacle and put plans in place for if and when the obstacle or situation pop-up. They are like programer planning the desired outcome of the program, their lives. Like the programmer they put if and where variables in place. If this happens then I will respond this way and when this happens then I will execute this formula.
One person plan his life and the other is just living his life. Life will allow throw you challenges, it is our responsibility to be prepared to respond to the challenges.
