So for most colleges they want some activities for a few years. Regardless what you did. One of the best activities is actually a job.
If you just hung out great. What did you talk about? So maybe a weekly discussion group on???
My son had multiple ecs but one was just a group of students every week they went to check out a different activity /club at their school They were weekly exploring different interests, ordered pizza and had fun. This has value on a college campus. Not everything has to be curing cancer. The AOs want to see your active since then it’s a good chance you will be active on their college campus and bring value and worth to their college.
