You probably don't want to hear this, but you need to hear it.
Your real job as a sponsor is simply to get people signed up and started.
Sign them up, train them for an hour or two, and help them get one or two people signed up.
You aren't their boss, parent or therapist.
*** Don't make the mistake of trying to be one of those things to your team.
Each person is responsible for their own business.
You are only responsible for your own success.
You can't drag anyone across the finish line or make them successful.
Just help them get started, be accessible and lead by example.
That's the best thing you can do.
If you think it's your job to make other people successful, you will get burnt out and eventually quit.
Remember, this is a volunteer Army and each person is their own boss.
