Because the reality is, any kind of work you do to improve your dating life won’t actually improve your dating life. Everything you do, you should do for yourself.
There are things that you can do that will make you more attractive to women. You already know what they are. Lose weight, exercise. You don’t need anybody to tell you to go do these things. The problem though is that they’re hard to do and if you do do them, your dating life will only improve marginally.
Because they’re hard and only marginally effective at what you’re trying to do them for, improving your dating life, it’s only really worth it if you do them for yourself, if you go into it for the reason that you’ll get lots of chicks after you slim down and buff up, you’ll get frustrated and eventually quit, not having really slimmed down, buffed up, or even gotten any dates. It’s a long road to walk alone.
That doesn’t mean you shouldn’t eat less and exercise. It means that if you’re going to do them, you need reasons that stem from inside rather than outside to do them. It’s not about making the ladies do something, it’s about making yourself feel something. If you are confident inside because you feel good about yourself because you used to be huge and now you’re svelte, that’s worth the effort. Bonus, women will like that too, they’re drawn to that kind of confidence.
In short, it’s your mentality that attracts people to you, not anything you are doing in particular. You could be lounging around your house for 14 hours a day and still be rolling in female attention if you were confident and authentic enough.
