After designing my ideal week, I had a much clearer idea of how to create a framework for my week that would empower me to feel more focused by theming days of the week, and even parts of the day. I spent nearly a year turning down every new project (and even getting rid of old ones) so that I could reduce my workload, build in more margin, and create what is now Digital Strategy School. It takes time to build margin into your schedule.

Every selector has the potential to have unintended side effects by targeting unwanted elements or clashing with other selectors. More surprisingly, our selectors may even lose out in the global specificity war, ultimately having little or no effect on the page at all. Any time we make a change to a CSS file, we need to carefully consider the global environment in which our styles will sit. No other front end technology requires so much discipline just to keep the code at a minimum level of maintainability.
