100% worth it. I taught Rifle/Shotgun during summer camp for 2 years, with some other events outside of camp, and the look on their faces when it "clicks" is satisfying EVERY.SINGLE.TIME.  Feed the bureaucracy their paperwork so you, and the scouts, can reap the rewards. 

And the obvious fact our small units NEED the adult help is often why we do not get the cubs to join us.  They go where the group is larger and has the adults involved more highly and in larger numbers.  You can almost see the parents thinking as the politely thank us for the visits.  

Yes. It is worth it. I will soon complete my first year as MB counselor. Also ASM for the troop. It is amazing to watch scouts grow, learn new skills, and bring them back to the troop. There seems to be an all-around registration issue going from paper applications to electronic. I am stuck trying to renew. The prompt says to renew in the electronic system but nothing about my MB counselor position is in there.

I found the call to action years ago when I rejoined Cub Scouts with my son. It became apparent that the Pack would quickly fall apart if new parents did not take on any leadership roles. It took me about a year to relearn the program, another year to find a place because we had a dedicated den leader, then we were running the show. Out of 8 youth that joined my son's new den as Tigers, at least 6 of their parents eventually became registered as leaders: Den Leaders/Cubmaster/Committee Chair/COR/Treasurer, etc. I had skills to bring as a former scout. But even parents who had no past experience in the program found the value and stepped up.  Today it seems like a harder sell. We got parents to bring their kids to join with established leadership. But they sooner walk out the door than take on a leadership role themselves. Even parents who were formerly scouts. 

I came to the realization decades ago that the first step upon assuming a role in Scouting was to start looking for a successor.  I thought that accomplishing that could take several years. It soon became apparent that my efforts would have scant success in that in a troop of 15 scouts, or so, with two pairs of brothers, leaving 13 pairs of parents as prospects, and subtracting me and the other 3 or 4 parents already active, and subtracting most of the moms who are welcome but show little interest, that left about  8 "eligible/prospective" successors.  Of those maybe one or two had been scouts…who had the time, the interest, the skills… You get the idea-the pool of prospects was very small. I'm in my fourth year of "retirement" from being Troop Treasurer, still serving as treasurer…I agreed to stay on for 2 years after my youngest aged out…that was 6 years ago, and no prospects in sight. I've had no better luck at district level positions.
