Organisation

I hate that word! I have all my life had a real problem organising myself regularly and efficently. Instead I go through stages of being really prepared, organised and efficent, making lists and using my diary. However once this period of manic organisation is over I am left floundering in a wave of emails and deadlines that I am going to miss if I don't pull my finger out. Right now my deadlines are undercontrol but my email-replying skills have suffered. I never seem to have enough hours in the day to do everything I need to do. I never seem to be able to remember important things despite numerous reminders in my diary or on my phone. My mum and dad often refurre to me as an 'air-head' in times of loving frustration and I always found that quite unfair untill today! I am HOPELESS at being truely organised. This can lead to bigger problems such as missing deadlines not necessarily to do with work.
Today for example I found an email in my Inbox which was was sent on Friday but I only read today because I check my mail so sporadically, I had to reply to this email by Friday evening or it meant I would get in trouble. Now although I find the fact that I was expected to check my emails more than once in a day, in order to get and reply to this email highly unfair and silly (surely he could have given me the weekend!) it was my own fault!

I always say I will do things "in a minite" but don't often get round to them till a couple of days later....that is WRONG!!

And a couple of weeks ago I missed the start of a shift at work because I assumed but didnt check the time of my shift to see if it was different from the week before.
This is me being hopeless and disorganised in the worst way!
What can I do to solve this? Help!
