Reddit reviews Become The Most Important Person in the Room: Your 30-Day Plan for Empath Empowerment (Empath Empowerment® Book)

I've had this kind of thing before too. At first I thought I was sensing the future somehow, but after learning I'm HSP, and empathic, I now realize I easily pick up other people's "stuff"--what they think, feel, and want--though it doesn't come labeled as someone else's, so it's hard to tell whose it is. I also tend to be passive, so what the other person wants often does come to pass--makes it seem like I foresaw it, but actually I just felt their desire long before they made their desire into reality.

I've found this ability comes with major drawbacks, and I went looking for ways to have better control over what I'm picking up and from whom. I found a rather woo-woo book for empaths called Become the Most Important Person in the Room and I have to say it's really helping.

As u/scippie implied, how much you pick up has a lot to do with how much attention you pay to someone and how much interest you have in them.
