I can relate. Surprisingly, I am pretty good when I'm at work. I am able to keep up with the method of trying to prioritize and get the most important stuff over with, because I am very, very forgetful.

However, in my home life outside of work, I procrastinate a whole lot. I am terrible at keeping up with financial stuff and wait until the last minute. I wait until certain rooms get cluttered and then give up on doing anything about it until a much later time. Mail is hard for me to keep up with. I hate housework and have a hard time with it, although it's part of being a "grown up."

I do believe the above suggestions are good ones as far as breaking tasks into smaller steps. Also, do not beat yourself up about it! We all have strengths and weaknesses. Some acceptance, while trying to make small improvements is a great start.
