become organized

this is one goal that i despair of ever actually happeingng. i am naturally a very unorganized, spontaneous, unplanned, messy person. and so whenever i try to become more organized, i fail miserably. i honestly dont know how to even start becoming more organized. amy ideas?
i would really enjoy actually being someone who finally writes down her plans, and things to do in a calendar, to organize my house, and to organize my information that i need by making neat lists. i am exactly the opposite of this, so becoming organized is a big goal for me.
