Good question man. In my opinion, it is by overcoming progressively "harder" situations. If you are trying to get a strong frame when it comes to talking to women, then these should be social situations. After having gone out with hundreds and hundreds of women all over the world. It is hard for me not to have a pretty strong frame. It is because I have been in all these situations for years and thus my subconscious is confident in my ability to handle additional ones.

Let me know if you need me to elaborate on that
