I have a hard time saying NO to fun or educational things. I am also a “helper”, I like to help people. I get tons of ideas too. They ALL sound good! LOL I already have a full plate of stuff going on in my life. You may have a similar thing going on for you. I’m going to share with you you what I do.
Before I say yes to another opportunity or responsibility, does it fit into my life right now or will it take away from what I am doing? Then the answer will come to you.
