I have usually organised many of the GN meetups in my town, but when I couldn't, or didn't want to, I said so clearly. Others have done it perfectly well. The most recent one was planned and executed by Jane10. She took it on without "leaving everyone else to run around for you" and did so fine without me stepping in after she had it all in hand and mopping up supposed omissions and mistakes, If she hadn't, I don't think I would have gone in and corrected her mistakes, she is a grown-up.
Don't beat her around the ears for stating the obvious - that you reap what you sow.
If you insist on redoing what others have tried to do, then it has become your project once again, and they are just your incompetent assistants. If you redo your children's homework instead of leaving it as their work they have only learnt that mother does it better, and if you don't allow others to take on some of your responsibilities and live with the failures they never gain the confidence and experience to do it better. That applies to people older than you as well as younger - they don't have to be totally dependent on your perfection unless you insist on applying it.
Let's face it, being indispensible is a highly satisfying sensation.
