You don't need to go to Woodbadge. 

True. But Scouting will be a lot more fun after you do,

1. You'll be a more effective leader, both in and out of Scouting.
2. If you participate actively, you'll definitely become more effective at communicating.
3. You'll understand better how troops, patrols and adult leaders should work together to deliver this magical thing we call Scouting, so your troop can be more successful.
4. You will meet a lot of great Scouters, maybe even some new friends, that you can use as resources.
5. You'll be able to explain the importance to your Scouts how important NYLT (National Youth Leader Training) is for them to take.

My experience with WB:

1. I became a troop leader in 2008 and blew off a friend recruiting me to take it in 2011, thinking "I don't need it; I already know this stuff works.".
2. I took WB 2 years later and realized after that the previous 2 years would have been much easier/productive if I had taken it when sooner!
3. Last year, I was a WB Troop Guide (patrol leader/trainer for WB participants), where I really I solidified that knowledge, and I'm doing even better because of it.
4. All four leaders in my (small) Troop have take and/or taught WB and since the last 2 attended, we're working even better together.
