Best of luck Yen. the training diary is a good idea. I keep one, the Joe Friel bound diary from Velopress. I found it at Amazon.com, here is a link if you want to see what it has to offer:

I like the daily set up as well as the sections for zone training data and a section for test results if you have them done or conduct them.

Hope this helps you in your goal, mine has been a nice addition.
