Scout, Skilled Liar, Deft, Skater, Autodoc Specialist, Addiction Resistant, Tough Feet, Packmule, Outdoorsman, Indefatigable, Light Step, Accomplished Sleeper and Fast Reader/Leaner could all be acquired one way or another (mutations aside ofc).
Stylish, Gourmand, Bookworm and etc are more about your character’s personality than anything else, and not really tied to skill levels. A person can become any of those, but it’s not something that happens overnight (unless the player finally discovers the joys of cooking through necessity or something).
