I've recently started trying to widen my skill-base in order to become a better employee. I'm sure there are some avid self-improvement freaks on SF, so what skills have you given yourself? Good books to read? Mine are mostly people-centric as I'm currently in Sales and going into Marketing and PR when I graduate. Body Language The Definitive Book of Body Language - Barbara Pease Artful Persuasion: How to Command Attention, Change Minds and Influence People - Harry Mills Sales Technique Not many good books on this one, but I've personally found a couple of Mentors over the last 3 years who have all been amazing salesmen. Its got to the point where I could conceivable sell almost any idea or product. Any good resources for further sales technique? There's always more to learn. Graphology Generally a bullshit subject, but there are some nuggets of information in there such as the opinions and attitudes of people who have written notes on particular subjects. Scheduling Not necessarily a skill so much as a tool. Mostly learned from blogs such as Study Hacks and Steve Pavlina. Its amazing how much more you can get done in one day when you break your day into 1 hour blocks. So what have you learned, read or wanted to learn thats made you a more successful professional?
