In a way, education by its nature favours the extrovert because you are taking kids and putting them into a big classroom, which is automatically going to be a high-stimulation environment. Probably the best way of teaching in general is one on one, but that's not something everyone can afford.

Your tendency to be inward-directed or outward-directed is huge; it governs every part of the way you live and work and love.

Opposites attract, and I think temperament is so fundamental that you end up craving someone of the opposite temperament to complete you.

In our culture, snails are not considered valiant animals - we are constantly exhorting people to "come out of their shells" - but there's a lot to be said for taking your home with you wherever you go.

Introverts need to trust their gut and share their ideas as powerfully as they can. This does not mean aping extroverts; ideas can be shared quietly, they can be communicated in writing, they can be packaged into highly produced lectures, they can be advanced by allies. The trick for introverts is to honor their own styles instead of allowing themselves to be swept up by prevailing norms.

Everyone shines, given the right lighting.

I'm continually amazed by how many people who appear to be extroverts are actually introverts.
