Re: Any Scouting Leaders here?
I was a Scout myself, but my career in youth leadership as an adult has been with Outward Bound, the YMCA, and a private summer camp.
I wouldn't say any youth leader has an easy job, but the amount of structure in the BSA makes the job a little easier because the program development has all been done. You don't have to "invent the wheel" because it has been invented and developed over a century. The BSA is probably the most structured youth program in the US, even Rainbow/DeMolay groups don't have all the rules, creeds, uniforms, badges, and ranks of Scouting. So my advice would be to just follow the program and help kids earn their badges/ranks.
As with any program, remain focused on the Scouts and that will help you out when it comes time to make sacrifices (and you will, your time and money, stress, ingratitude from kids and parents who don't realize all you do, etc.). You will then be immediately able to answer your own question, "why am I doing this?"
Also look for those wonderful events that I call "light bulb moments." They are those instances when the mental light bulb comes on . . . when a kid finally gets it and you can see it on his or her face. It may come after hours of hard, sweaty uphill climbing, but then when you see the view from the top of the mountain everybody's mouths fall open with a "Wow . . . " Or you might be trying to teach a Scout something for the fifth time and then they try it and they can do it. You will work for hours, days, even weeks or years for those moments but they are absolutely worth it.
Okay, that's all I've got for now. Hope it helps.
