Overall, the number one most valuable skill in my opinion, and the one that I keep coming back to over the years is critical thinking. For that, I love Understanding Arguments, the Philosopher's Toolkit & Ethics Toolkit by Baggini & Fosl, and anything "legal", which sharpens your critical thinking, like Farnsworth's Legal Analyst or even Intro to American Law on Coursera. But those three books on basic reasoning will serve you well for the rest of your life as a business and technical leader.
