The issue that I have is that things change, a lot, and usually without much notice. The only things I can truly put on a calendar are birthdays, holidays, and actual appointments, anything else is fair game. I can plan things a couple days in advance, but generally I am up against someone else's schedule, waiting for something from someone else, at the mercy of the weather, or trying to deal with an "emergency". Essentially, when I plan things out, it just turns into a rescheduling nightmare, so I have learned to go with the flow for the most part, just gets frustrating when weather is bad and things don't align well. I think breaking things down by costs, time involved, location, and relative priority should allow me to do a quick search when my schedule changes. Once I find something that fits the available criteria, then I can at least be working towards a project or goal rather than almost creating new projects or just wasting the time.
