In my opion Focused subs are great if one has a specific goal at specific time in life and is willing to ‘sacrifice’ or let go of less important priorities for that.
That said Khan, Stark, and Emperor cores all probably cover the main areas of wealth, romance, intelligence, confidence and character.
I think the value of a sub that has multiple effects and goes in multiple directions is that they can integrate and become more trait oriented as part of the total package of who you are. Rather than training to be in consistent specific state that becomes a trait. Like pure productivity or pure socializing.
From my view, If you want to be someone who can have it all, and goes from meaningful work, to dating/meeting woman to creating… or whatever it is one wants, then train for that. I liken it training for a sport like MMA or crossfit. You have to train all the specific physical attributes for the game to be able to perform across the spectrum. Training multiple traits: speed, explosiveness, maximum strength, mobility, consistently to progress most fully as an athlete. Now if you have a much more highly specific sport or goal you might not do that. Or if it is an off season and you have the space to focus on one specific skill set you might choose that.
For example On EmperorQ I can move from studying intensely, socializing, leading, working, contemplating, planning, and executing my larger vision, meeting woman, seeing woman etc and I feel confident and capable in all those areas with minimal trouble shifting focuses.
This may just be me but If I’ve run Mind’s Eye, Spartan, or Power Can Corrupt-they are very different states, even though the characteristics of Emperor are still there, the lead note is different, and what’s at the forefront of my thinking is different. I wouldn’t want to do certain work after PCC, and I wouldn’t want to go to a low key social situation after Spartan.
