On LE I have ground 12 hours straight without feeling tired

On Limitless Executive I have had days where I grinded 12 hours without feeling tired. After establishing that foundation, switching to 30-second daily loops brought even more consistency — the mechanism is that the short loop reminds the subconscious of the full integrated program, like hearing one line of a song and having the whole track play in your mind. This brought me to a consistent 7-8 productive hours daily with no recon, every single day rather than just once or twice a week.
