Welcome to scouting, I have been Cubmaster for five years, I remember feeling the same way you do. I was afraid that I wasn't doing a good enough job or that maybe I just wasn't the right person for the position. I was a wreck and I asked my wife how she thought I was doing, I'll never forget what she told me. She said you know what at least your doing something for the kids and thats more than a lot of other people. Remember to always have fun with what your doing I love to call on boys for advancement and then pretend I've lost it or something to that effect and they love it to. Forget what people think about you and and have fun with your Cubscouts, you are getting ready to make friends with some of the best people I know CUBSCOUTS!!!
