What is a better self-improvement strategy of these two?

Stargtegy A

For me I start my day with some easy wins (these don't have to be work-related could be exercise or meditation or something). And then move on to First Things First. This mini "clear the runway" helps me get early momentum but still allows me to focus on important tasks first.

Strategy B

"Clearing the runway" often ends up being a distraction from working on the most important tasks, which are typically more difficult and more likely to cause us to procrastinate. Ideally, I like to work on "first things first" early in the day, but I try to block out time to "clear the runway" later in the day.
