Can somebody explain it to me?
If it's about people you can attract then all people stay in their league by definition. Kind of also unnecessary term.
If there is a dating "above" or "below" your leagues then who decides what puts someone "above" or "below"?
I've seen that it's about who you can make commit to you, but we see that women want commitment so it's easier for men? What if you in the stage of life you don't want to commit yet?
If it's about looks (maybe not only but about looks too) then how do you measure your attractiveness?
