Figuring things out

I am trying to keep up with life in general. Between work life and home life I don't know which end is up. I need to find a system to organize myself and try to keep track of all the things I need and want to do. I will be going about my normal business and a though will pop into my head of something I want to do and no sooner is the thought there and it suddenly disappears from my mind. Sometime later it will pop into my head and I wonder why didn't I remember it the last time.

I have tried a PDA type thing and that failed. I tried a normal calendar to carry in my purse and I keep up with updating that about once a month but that idea always seems to fail. I tried adding things into my outlook calendar at home and that never went anywhere. I even tried adding things to my work calendars. Nothing works for me. What other options do I have other than to get a brain transplant to add more memory space?

Currently I have a number of things I have to do but always remember at very inconvenient times. I am going to end up missing the opportunity to make appointments when I need them. I am going to become an outcast to my family and friends because I seem to always forget to call them even to just say hi. I almost never remember to acknowledge birthdays. I might forget my own birthday if people didn't remember it for me.

What's a girl to do?
