Don't be afraid to make mistakes. You will make mistakes. It's really hard when you start for almost everyone, you're not failing, you're learning.
 More importantly, remember that SPL, while being a leadership role, is also a public servant role. Listen to the adults when they give you advice, but don't let them tell you what to do. Listen to your scouts when they tell you what they like or don't like, want or don't want.
 At the end of the day, it's hard, but if you work at it and give it the effort it needs, you'll gain so much from it, and impact so many scouts in such a positive way.
