I respectfully disagree with that statement GernBlansten.
My son is 17 and has not lost the spark. He is too active with other things to concentrate on working on his Eagle all the time. Yes he does need some pushing, but he is still VERY active and has not lost the spark.
He works with the younger boys in our troop, plus he helps out in the pack I am still with. He volunteers at any event our council asks him to. He is currently working at Boy Scout camp for the summer.
This is a boy who joined Scouting in December of 2000. Earned Scout in April of 2001, Tenderfoot in May of 2001 then Second Class in June of 2001. Then that is where he sat. His former troop believed in the ultimate boy lead troop. If the SPL said they were going to play basketball for 1 & 1/2 hours each week, that is what they did.
Well, he was bored. We started a new troop up in the fall of 2002, and he was one of the first 5 boys. Things were being organized, and the boys were being taught leadership skills. By summer of 2003 he made First Class. July of 2004 he earned Star, and July of 2005 Life. Yes he took longer than the required, but he was/is having fun.
Will he earn Eagle? I sure hope so, but if not, I know that he has had a blast along the way. Does he still have the spark, you bet.
He even plans to stay in Scouting after turning 18. He wants to help some of the younger boys in our troop on their trail to Eagle.
So, just because a boy doesn't earn Eagle by 16, I don't think he as always lost the spark.
