What are some micro changes managers can make to become a better leader?

Obviously it’s about the foundations, but small habits can have big impact too. I’ve noticed a few small things leadership has done or that I’ve done that I believe to be meaningful. I’m wondering what experience and suggestions you all have?

Some examples: Changing weekly 1:1 with direct reports to 45 minutes (versus 30). Adding the entire team’s birthdays to my calendar and making sure to tell them happy birthday. Taking 15 minutes a couple times a week to swing by my skip level reports’ desks to chat about something they enjoy (movies, music, gardening, etc)
