Seth Klarman a hedge fund manager from the Boston, Massachusetts area that I have admired for years and author of one of my favorite finance books "Margin of Safety" has a great quote in a recent Harvard Business School speech. The quote is "A big part of leadership is deciding, and good decision-making benefits from intelligence, thoughtful deliberation, and experience, but also, as i hope you agree, from sound values."
Other great lessons in the piece can be found here for my reference: https://www.alumni.hbs.edu/stories/Pages/story-bulletin.aspx?num=6818
