I always hated the hobbies advice because it's old, boomery, and most of all misguided. The way women and men spend their time just isn't the same. Even today when nerd culture is at its peak, you aren't going to your local Magic tournament and finding your forever waifu. If there's even one girl there, she's probably with her boyfriend. If you guys want girlfriends, you go to where women ARE. Whether it's bars, events, concerts, or just in stores. You go to where you expect women to be. Maybe it'll be hobby adjacent, but if these old boomer faggots expect you to meet of the love of your life at a hunting convention/expo, they're gay and retarded.
You want dating advice? It's real simple. Go to the gym, get in shape and take care of yourself. Then just talk to women, anywhere. Yes #Metoo is a thing, keep that in the back of your mind. Avoid online dating apps completely. Women are under ZERO obligation to respond to you. You will get nowhere fast. When you just be a good conversationalist, you'll get whatever you want. Once you do that, always remember, women will do ANYTHING for man they really want. They'll abandon their own children, break the law, and take beatings every single day for a man they love. If you are not that man, do not marry her. You have to really pay attention and fish out if there are any signs like that. That's how you keep yourself from being 55 and divorced or married and miserable.
