Hmm.

Has it helped you a lot in life?

Well, it's hard to say; maybe it hasn't reduced the number of failures, but who knows, maybe there could have been even more!
There were, of course, a couple of moments when I could have easily ended up in the afterlife, but I'm not the kind of person who attributes all of that to some kind of "miraculous rescues."

I'm asking because I was told that if I always wore it, things would be better.

Well, yes, you can't really verify that now. And who knows, maybe everyone would be healthy, wealthy, and successful. So, no, unfortunately.

In short, if this item really helps you to gather your thoughts and/or restore a positive mood, that's already good. Personally, it doesn't have that effect on me, unfortunately.

Nice avatar, by the way...

Thank you, yours is nice too!
