Everything that the article talked about is true. How do I know? Because my mom has been telling me and my siblings this since I can remember. (Full disclosure: I love her and have a healthy relationship with her; she's awesome, but this won't be about her, kind of...) I've asked her how she does it, how she can just walk up to anyone and have an awesome conversation with them? How is she so fearless? Well, for one, she's a lot older than I am and obviously has had a lot of practice, so practice is key! Secondly, she is the most sincere person; she truly wants to know the person she's talking to and cares about what they have to say. Through her sincere conversations, she finds a way to connect with them, and before we know it, she's made another friend. So, this reading was on point because I've seen it all in practice for years.
