Since nobody else is saying it, let me be the first to tell you what your problem is, it's the same problem 97% guys on this forum have.
Your to busy trying to be "Alpha" or "hard to get"
"Not look like a simp"
That's your problem, your not being natural, your so busy worrying about not looking like a simp that your looking even worse......
The red pill and pick up in general is more bad than good for most men because they start trying 2 hard and mentally masturbating to the point that it's damn near impossible to come off attractive to women.
Your trying to put out this false persona(and it's definitely false because your here asking for advice on what your doing) your being something your not, don't worry about being a challenge, you guys make this more complicated than it needs to be, just engage with women bruh.
Learn to have some charm to you and get rid of that fake wannabe alpha or whatever your tryna express to women,
Stop worrying about gaming women or acting a certain way to attract them and just engage with them, your suppose to be fun and exciting to be around, make them feel good, charm them......
Women don't fvck guys who act the way you do, they will just think your weird, meanwhile your sitting around thinking to yourself
"Yeah I showed her, I'm no simp" lol
Being a challenge is not something that needs to be taught or thought about lol it's natural.
Just focus on yourself first and your good.
I'm not going to give you tips because your just going to overthink it......
The girl I'm currently dating now thinks I'm a challenge because I dont text her back fast enough and often leave her hanging mid text conversation, but it's not some game I'm playing lol I just suck at texting and I'm busy doing other sh!t.
Sometimes I go weeks without fvcking her or hanging with her, why? Because I'm a introvert and don't always feel like other people's company, I turn down invitations to bang from her all the time simply because I just don't feel like being bothered at the time, I guess she takes it as a challenge, it's not something I consciously think about.
You need to chill brotha and just relax and act fvcking normal.
