It's a good advice. Although, I noticed if you aren't performing well your chances to get new friends in hobby societies are lower. Especially in team activities, like volleyball. So it probably makes sense to choose a society for a hobby that you're good at.

Another observation -- finding new friends usually requires spending money for social activities. That's OK, but one has to be ready to spend more money than usually. I'm not saying that "free" activities never work. It just gives you fewer chances.
