Choose the thinking skills you want to keep using.

The six Skills

• Skill

  Writing

  Short daily reps for the sentences you still want to write yourself.

• Skill

  Math

  Mental math, estimation, and numerical reasoning kept in the loop.

• Skill

  Code

  Reading code, predicting behavior, and reasoning through logic.

• Skill

  Memory

  Recall, association, sequencing, and working-memory style reps.

• Skill

  Reading

  Attention, comprehension, inference, and recall in short daily passages.

• Skill

  Reasoning

  Logic, deduction, comparison, and decision-making in seven-minute Sets.

Why these six

Each Skill maps to one kind of thinking that AI assistants can quietly handle for you — drafting a sentence, doing a calculation, predicting code behaviour, remembering a fact, summarising a passage, weighing a decision. The point is not that you should never use AI for those. The point is that if you stop doing them at all, the practice fades. Senwitt's answer is a small, mixed daily Set across these six categories.

The six were also chosen because each has its own research literature — not a marketing one. Writing has the MIT Media Lab preprint on LLM-assisted essay composition (your brain on ChatGPT). Code has Anthropic's own coding-skill-formation study and the practitioner literature on skill atrophy (programmer cognitive skills and AI). Memory has the GPS-and-spatial-memory natural experiment from UCL (GPS and spatial memory). Math, Reading, and Reasoning sit under the broader cognitive-offloading research (cognitive offloading).

How Skills work in your Set

You can re-pick which three to six Skills you want any day. The mix in your daily Set adapts to what you chose. Picking fewer Skills means more reps per Skill in a single Set; picking more Skills means broader exposure and fewer reps per Skill. Both are valid patterns. Senwitt's default is four Skills, which tends to feel like a balanced Set without spreading too thin.
