Organizing the content of your life based on your needs is a best practice for managing your time, resources and money and is an essential first step if you are to fully achieve your potential in life. The reasons for this are simple. An organized clear mind leads to clear and objective goals, which in turn leads to you being able to achieve what you set out to do.
A critical first step then in staying organized is to set up a system of resource planning and clerical needs that allows you to plan out your time effectively, and allocate where you are going to spend it. In short this means such steps as getting a day planner so that you can plan ahead. Getting appropriate stationary systems and office space in place, and also getting yourself a filing cabinet, or at the very least some kind of filing system!
It would certainly be true to say that staying organized then is not something that lots of people do naturally! At first it can even seem slightly stifling, especially if you are used to totally going with the flow of what each day brings. In truth this is ok. It IS good to be spontaneous on occasions, but in general it is vital to plan out what you need to do...
