September. The time of the fiscal year where everything resets and becomes new in school and business. Even though every day, every week, or every month can be the start of something new - this is the time when organizations recognize it from a clerical standpoint.
Its a good time to record how much has been accomplished. Growth starts by having an awareness of where you currently are. That awareness has you see how far you've come along and where you are on the track of where you want to go.It's not the type of reset where everything you've done prior to now vanishes but rather you continue to build upon it. Now you take the point where you're currently at and use it as a new starting point to your next goal.
And therefore you continue to move along your path of growth.
