Challenges to help me out of my comfort zone and improve my confidence / social skills?

I want to spend this month really trying to push myself through various challenges to help me push out of my comfort zone and help to improve my social skills and confidence.

I started this at the beginning of the year and so far have been able to do some challenges such as going to the cinema, going for a run in public, having a coffee in shop.

But I'm struggling to bridge the gap and to think of additional challenges. So far I have the following.

1. Cinema trip. Continuing to go to the cinema, aiming for twice in the month.
2. Shopping centre and coffee in-shop.
3. Going to a local car-boot sale or flea market.
4. Going to the club for 30-60 minutes.
5. Going to an event at a bar/club for 30-60 minutes.
6. Continue running in public.
7. Content creation. Streaming games online, or making content for Youtube/Tiktok. (Not sure about this one).

I also had the idea of going to a gig in a different city but it would be so expensive so I'm not sure.

Any other ideas?
