Time and timing are everything...

My aids to not burning the dinner, remembering to make the call back, taking out the bins and all sorts of other mind jogging requirements..

Is it just me or does anyone else find that they remember things several times on the run up to the event(s) and then - forget them?
When I arrived at school yesterday I had forgotten a set of books, some money and my mobile. The books were even beside the door... but the post man came just before I left...
The day before... I have forgotten what it was I forgot - but I know I forgot something... if you follow!
I put things on my phone, in my diary, write lists and stick post-it notes up but none of these are fail-safe! I also use these timers if I have to do something within an hour...
