A subreddit where people discuss something to practically do it, and then come back to report how it was

What title says. I have a good example: People who either want to get rid of their social anxiety/awkwardness or just want to reach excellency by trying different (and even profound) ways or methods to expose themselves to certain social stimulus. And report the feedback when it's done. But it's just an example, it can be anything.

You might say this casually happens in most subredditd especially nieche one but i am looking for one which has s primary goal of 'act and feedback's
