To get a girl, the minimal you can do is to make her feel that shes unique in her own way, and to you as well.
No wonder some Mr Nice Guys don't/can't get gfs - simply because they're nice to everybody and anybody that girls don't feel that they're special to them in any way.

so Ironic. So Mr Nice Guys - refrain from being too nice, widen the gap of sweetness to people. Focus more on the 'You-should' and dilute it as it sinks to the bottom.

Good Luck
