@lilaznstar235, if you can’t come up with a good idea, and are time-strapped (start-up clubs take about 20 hours a week of time, or more), you may want to look at starting a local chapter of an existing organization, like the Red Cross, or Ignite, or Planned Parenthood. (Katherine Klem of Ignite has been a friend of my daughters since 3rd grade.)
Pick something you like and stay with it. Leadership is not always about creating a club. You could pick something that is about providing community information. As an example, if you are teen with a chronic medical condition, and get dropped from your parent’s health insurance, how do you get your medication covered?
Or you could do a community outreach project on the dangers of sleep deprivation.
