zdarova, kak dela?

.
now, forget all about this "show that she really dosent
mean anything to you, " this is how you repeal girls from yourself. This is used in a "game" type thing where you and the girl are trying to see who wins. It is used on girls that you truly don't give a shit about and ones that are into you. Otherwise it won't work.
You can show indifference, which is a great force by itself, but indifference itself is very much like accepting everything. It is NOT having the "I don't give a shit" attitude. So use that instead of what you wrote.
Well, you really seem like you got most of the "common" material stuff down and you are ready for truly above-mediocre results with girls. Depending on your age it's going to be +/- 1-2 girls a month. If you quit your job and make this full-time you can sometimes even bang 1-2 a week.

There are better ways though... but try this and see for yourself, then move on to more advanced things, which are out of scope of this seduction community.

Wish you luck!!!
