Reading: Presentation Zen
Giving presentations is a big part of being a scientist. Even in industry. Anyone can give a talk. Not everyone can give a really effective talk. Taking all your fantastic data and making a compelling presentation is as much an art as a skil. This month I'm recommending Garr Reynolds' book "Presentation Zen" which has some fantastic advice on how to improve your presentation skills.
It's well worth a read. Or two. Reynold's also has a website, presentationzen.com, with valuable tips on presentations.
