Use The Law of Assumption as taught by Neville Goddard, not the Law of Attraction you know from modern new age culture. Less retarded, more straight forward. Makes all the difference. The first five lessons of Neville Goddard are all you need, his other works are easily findable in PDF form, too. Practice earnestly, maintaining your focus as effortlessly as possible is key. Make it a habit of trying to get into SATS every night. Get your sleep schedule right, cut out short form media and things that ruin your attention-span/sleep quality. Choose a scene that actually implies you two are together romantically as neville says.

When choosing the personality/appearance for your new gf, be very careful and specific. Know just who you want. SATS for someone who is too different from you/just plain crazy at your own peril. Dont manifest someone just to have to do more SATS after the fact just to make the situation not a headache.

Another tip: Dont be the headache. Genuinely self-reflect on your assumptions about women, love, sex. Rid yourself of any useless blackpill states you've assumed. If youve assumed deep seated insecurities they may reflect in your reality. If you think all women are cheating whores, guess whats probably going to happen to you?

Last tips: When visualizing, dont worry about not being able to hold a 1:1 picture of the girl you want. It's the intention that matters, that you know and feel in your heart that you have what you want RIGHT NOW when visualizing in SATS. That the visualization IS the real thing. Keep going every night until you get so deeply into SATS that it truly feels like you stepped into your scene and are really there with your desire as Neville says. If you make it to that point it'll happen super quickly.

Keep it simple, take things one desire at a time at first, dont go crazy literally or figuratively. Everything you manifest will come to you as if it always was going to. Dont worry about the how of things. Good luck, anon.
