Hi Lucy,
Right before the heading of your post caught my attention, I was reading this post: http://dev.tinybuddha.com/blog/accepting-yourself-as-as-introvert-and-loving-your-inner-tortoise/. There is nothing wrong with being disciplined and planning things ahead of time. In fact, I would love it if some of your discipline rubbed off on me. I could sure use it! I donāt see how this is āinternally disorganizedā at all. If thereās one thing I would advice, it would be to schedule some quiet time for yourself. A time for light leisure, reflection, or meditation. Other than that, really, weāre all different. Some people are spontaneous and some arenāt. I donāt see how this should hinder your social life at all.
