Here are a few ideas of the types of novel experiences I would love to have by 24 and to continue to have for the rest of my life. It really helps me get out of my comfort zone!
1. Travel somewhere new.
2. Try new foods.
3. Take a class in something that has always interested you.
4. Join an intramural sports team.
5. Start a new hobby.
6. Join a social group.
7. Try something extreme like bungee jumping or skydiving.
8. Win a contest/giveaway.
The Ideal Me by 24 
I joined a kickball team [at 27] and I’ve been enjoying it now for two years! It’s a CoEd team and a ton of fun!
That sounds like so much fun! That’s exactly the type of thing that I would like to do, too.
Have you searched your area? Pretty much every major city has CoEd leagues! Just $30-$50 to sign up!
I haven’t checked yet, but I really should! Thanks for the tip. 🙂
