Motivation
Keep your team members motivated.
Get their input, and let them know that you respect and value it. Give them credit for their contributions and good ideas.
Help them develop new competencies, so you can trust them to do more. Be their safety net when they are learning new skills or taking on new responsibilities.
When you bring out the best in your people and make sure they feel rewarded, respected, and valued, they will continue to do great things for your team.
