trying to get a handle on June assignment


So I am totally puzzled with the ‘daily dare’. I don’t get “dares”. I remember as a kid thinking they were the stupidest thing, why would anyone let themselves be provoked by someone else to do something, probably stupid. So I don’t get it. I am trying to re-frame it in terms that make sense to me- so a daily challenge? something that makes me feel trepidation, but not too serious, something more light-hearted? Thank you for your help !
