I like the idiom that something “rubs off” on people but I am wondering if there is an idiom with the same meaning but from the other direction; in other words, I mean with the meaning that people begin to have a positive attitude -or any other thing for that matter- from it as in the quote below.

often used figuratively
▪Her positive attitude rubbed off on other people. [=other people
began to have a positive attitude from being around her]
▪I wish some of your good luck would rub off on me. [=I wish that I
would start having good luck too]
