Characters...do they ring true?

I've had several ideas for a new book series, so must get to work on this. Recently I've been working on revision after doing an extra online course on character studies with Meredith Efken.

It's an interesting experience setting aside how you would react to a situation...good or bad...and crawling inside that of your main protagonist. One of my male characters was emoting just a little too much, so I've been revising his actions and attitudes and understating this. Now he rings true. I appreciate his strength and his rather awkward way of saying what he really doesn't mean in order to cover up. Oh no, he's not about to let anyone see what's going on inside...except me, of course. Mm, it's nice being privy to this!
