QotD: Grown-Up Boot Camp

What are three things you want to learn, and three things you can teach others to do? 
Submitted by bookishbiker.

Wanna Learn:
- Sign language.  A few times in my life, I've been approached by people who signed and I really wished I knew what they were telling me.  I think that was the point!
- Conflict resolution. I learned some but it feels general. Not quite the types or scope I'd like.
- Scuba.

Teach:
- Better communication skills, including listening and comprehension.
- Computer/tech skills (combined with learning):  I do it, but the people I'd like to teach most aren't very receptive... (we're all bound by a common notion of complication... The trick is to absorb and process, ask questions and absorb again if need be.  I only say this because I hear "ah well, see, it's easy for you -- you're smart!"  And, okay... I'm no too shabby when it comes to learning. But it doesn't mean I haven't worked at it!)
- I dunno... You choose.
