I'm sharing based on my experience of +15 months with night game, events, and daygame. I have the 'easy' stuff locked down and struggling with the hard stuff.

Easiest:

Basic Flirty Conversational Frameworks: Put the getting-to-know-you questions in the bin. 1) Cold reads 2) non-sexual teasing 3) 'we' hypothetical scenarios. 4) Playful disagreement. This is literally just a bit more flirty than how you would talk with your friends. For some girls who are very sexual, this wont really move the needle much, its practically platonic, but for shy girls/average girls, they may not have been spoken to like this in person for a long time and will feel flattering.

Approaching and communicating with romantic/sexual intent: Going up to a girl tell her you like her style, or the vibe you had, suggesting plans for a date and taking her number. It will feel rough at first but honestly its so easy and then you pretty much realise that its a great way to filter for interest quickly. Unlike indirect game, social circle game its pretty straight forward and doesn't need that much tact. Some girls will love the directness and tell you they haven't been propositioned like this in a while.

Rejection indifference/abudance mindset: Eventually, after enough approaches and dates, you realise that most women are the same and very few really offer something meaningful and unique to you as an individual...another one will turn up with enough volume. Once you get some casual sex out of the way really question - what am I losing here? A wife? Or an opportunity to spend £30-50 quid and time on a date that might go nowhere. Eventually you burn leads on purpose and don't bother to put flames out. Better opportunities always come up.

Taking the lead: From conversation, to texting to set up dates, to dates. Once you break the feminist/Disney spell, you realise you are supposed to take charge of everything and women like it that way. Think "we don't negotiate with terrorists", "my way or the highway" (i.e let her go if she's not interested and don't placate to make her feel comfortable excessively )

Be Social: Do you hardly leave your house? How do you expect to meet women. Look at Instagram, Meetup, Eventbrite for socials in your area. Speak to people, some of them will be women, some won't. Just say yes. Get out of the comfort zone. General idea is to desensitise to the unknown, the uncomfortable. Stay in touch offer to make plans, expand your friends, could be wingman, could be a great loyal friend who can support you

Hardest:

Balanced life: Especially if you're reliant on volume for meeting women, things can easily get out of control in other areas of your life, which in the long term will make you less attractive.

Calibration: Integrating aspects of game, together at the right time at the right intensity, adjusting for the type of girl. Some guys will never get this right (myself included)...too autistic, bad learners, but this is a double-edged sword. Low calibration will reduce casual sex opportunities but will filter out women who aren't actually a great fit for you (i.e women who are also compatible with you on a personality level)

Creating and holding sexual tension: At first just escalating is a challenge, but once you practice physical escalation enough, it becomes easy to do the kino routine...but sometimes logistics or LMS can mess things up and off the tension is killed the game is gone and power is transferred...the true masters can have a girl sexually hooked even without much kino and begging for dates 2/3.

Pre-selection: Unless you already have this locked down its very hard to build this from scratch... think curated Tinder/Insta, mixed gender friend group with attractive female friends, meeting well connected people, private members club, developing a skill/talent that has you placed as a local celeb (DJ, photographer, musician, legend on local karaoke scene lol)

Self-image / real growth - Perhaps number 1
Many guys here, like me, probably missed the natural window age 16-21 to do a lot of the innocent teenage love/wild sleeping around phase...maybe you were overweight, were bullied, experienced trauma, didn't recieve the right kind of love etc. Even with a glow-up as an adult, you've learnt some game, maybe you have a good job...but do you really believe you are enough...have you really embedded the positive feedback you've recieved or are you still running the internal script from your teenage years? This is ultimately communicated indireclty everytime you are with a woman. Remember, they have to feel that you are better than her, otherwise she will feel resentful.

Hope this reflection helps, inspires, comment any further thoughts on what I missed.
