Motivation and Inspiration

Hey all, I'm hoping to find some ideas people have to inspire others. I currently have no direct reports, but I am trying to develop a positive change for my organization. The team is in cyber security. But it really seems like everyone is jaded and doing the bare minimum day in and day out.

One idea I had was to have a sort of ted talk weekly within the team? Where people give a 10-20 minute presention about what ever they want. Infosec? Cool. Chip tunes, your garden, framing styles in movies? Awesome. I just want people to engage in something they love. And my hope is that this just gets people talking and communicating. Which hopefully leads to positive day to day outcomes with work.

Any other ideas? Or maybe books/discussions to watch?
