Nobody likes to write documentation, and I'm not that different.
But today I was very happy and said "Thank You" to myself. A while ago I needed to install some software for a project. Now after my vacation, which apparently wiped a lot of my mind's hard disk clean, I needed to repeat the installation for a new environment.
Reverting back to my own documentation saved me a lot of time.
Maybe I should create a video on YouTube with my impersonation of Steven Balmer's monkey dance and substitute the words "Developers, developers..." with "Document! Document! Document!".
So take it from me: writing documentation before your vacation keeps you longer in your post-vacation mode ;-)
