On community.lifehack.org: presentation tips from a science fair competitor. Makes me wish I'd gotten into the science fair circuit!
I've given many presentations on topics like wearable computing,
embedded computing, Linux in education, and personal information
management. I used to think, "Oh no, they want me to talk about
wearable computing again?!" Then I realized that the more I talked
about something, the more comfortable I became with the topic, and the
more I could connect with a large audience. I started telling stories
and showing comics, and presenting became tons of fun.
I think I should hook up with a few other Toastmasters clubs so that I
can give the same speech to many different audiences. It's good
practice for me, and a whole lot of fun.
