How does Some Thoughts Concerning Education develop the theme of Habit and Custom?

Some Thoughts Concerning Education by John Locke develops Habit and Custom across the chapters the companion marks for this theme.

Locke repeatedly emphasizes the power of habit and custom in shaping both body and mind, arguing that gradual exposure and consistent practice can make even harsh conditions tolerable and beneficial, as seen in hardening children to cold or wet feet.

Locke argues that children should be taught through repeated practice until actions become habitual and natural, rather than through memorizing rules.
