Ask HN: If you could mold a developer that gets the job done, how'd you do it?

If personality and work experience were perfect, and you had absolute power over an individual prior to him working for you (think freshman year or high school) - how would you mold him/her? What concepts would you want him/her to know? What principles and best practices should he/she follow? What languages (limit to 2,3)?

Essentially - even though this question was asked numerous times in different forms and on different web sites - I feel all of them lack something. They either point you to learn x and then learn y. Learn about this principle and then about this. No one puts it together - they just throw around books, websites, tutorials. And while that is helpful to a point, fitting it together can sometimes be puzzling.

So, how would you mold and shape your perfect developer? (any type applies)
