Well done on your first commute! I have a feeling that you will only need directions for another few days, I have always found that I develop a more meaningful memory of my paths when I am biking rather than driving.

I would suggest riding your commute route down and back several times this weekend, I constantly tweak my route on the fly. Meaning that when I get stuck in traffic or I don't want to climb a particular hill, I can switch things up.

My commute path is dynamic and is always evolving, even after 4 years at the same job. I have lots of choices to extend or shorten my ride depending on my mood and the time of year and construction conditions.
