Sure, here are the most impactful changes, they may sound simple to some, but they had a big impact on me:

1. I had already been blocking out "no meeting" time of 2-4 hours a day to get work done, but during this time I would listen to music and sometimes check slack. The book got me to use focus mode on my Mac and phone, set a "heads down until [time x]" away message on Slack and work without music or any other distractions ON ONE HARD PROBLEM. My effectiveness skyrocketed and I was happier at work (the only downside was that I wanted to work more).

2. When dealing with a hard problem, taking a break, taking a walk and thinking through the problem using the framework he mentioned in the book, have used this method to solve multiple hard problems.

3. Forced me systematize how I end my work day and what time I end it (unless there's an emergency)
