I've been doing a fair bit of travelling lately. In an effort to “travel light” I've cut down on the number and size of technical books I'm carrying with me. This trip I've taken only “The Pragmatic Programmer” with me. I find so many technical books don't seem worth reading once, yet this one I've read a number of times. It seems to have the great quality that you can pick it up and find something that is seems to speak to you directly about the things you're having to deal with RIGHT NOW.
Also I've started listening to opera while flying - I always feel a burst of adrenalin when the wheels of the plane hit the ground (something to do with the thought that "if things go wrong this could be the last moment of my life", probably no different to walking across the street but the danger seems more apparent). Having some prima donna singing her lungs out at that moment only serves to intensify the rush.
