sure smells like gender wars in here...
if you want to get laid, make it known, but it probably isn't going to help you get laid all that much.
If you want a long lasting relationship, you should make it known you want a long lasting relationship.
Where that sort of falls apart is the latter is much more effective at getting laid, granted you're not afraid to hurt someone's feelings in the process. It leads to a whole lot of suspicion about the opposite sex, especially when you can't exactly read the other person very well (luckily, in most cases you can, but if there weren't exceptions, this wouldn't be a problem).
Another issue is people who want to get laid, and not much more, and think they're ready for a real relationship.
So, yeah, being a nice guy isn't exactly the easiest thing to do, especially not when every douche ("alpha") on the block is trying to act like you for the sole purpose of not having to wank with their right hand that night.
It's why some nice guys are introverts, too. People punish them because, now, not only are they acting like the douches that are trying to act like them, they also don't share the desirable traits a douchey person might have. They come off as creepy. The point of this article was to tell the actual nice people to do those desirable things, so they aren't as creepy, and actual genuine nice guys without flaws.
The problem?
It's more complicated than that. Setting aside the shy people who are truly, truly evil bastards without spines so they can't let the world know about their plans for a second holocost, nice people usually know that, yeah, acting all high and mighty like a supernova may get you attention, but it's also kind of a dick move. Anyone whose good at their trade can vouch for that.
Not only that, but nice people are also very aware of the fact that, by riding your way to popularity by just doing sort of messes up your perspective on things, and defeats one of the biggest things that make a nice guy a nice guy: their humility. Sure, if they're high functioning and rational enough, they may keep it, but I only know one person who has through fame, and even then, it's not completely in tact: The Game Overthinker.
Also, don't get me started on the gender wars. It can go back and forth all day, and with good points and counterpoints, but ultimately, musicians > both genders. Deal with it. You have no idea how mindfuckishly useless music theory is for everything but music. At least with chemistry you can do something like... solving the energy crysis, or something that pays even more like cooking meth (what)!
