Yes, that's the right attitude to take with this disease. The main criterium is that you've been in or are in a region where ticks are found, combined with warm/hot weather.
Also, if you're in one of those areas, check yourself thoroughly for those tiny deer ticks every twelve hours. If you find one, pull it off without squeezing its abdomen. That'll greatly reduce the chance of transmittal.
You can get a cheap little plastic thing called a "Tick Twister" at the pet store, and it is awesome. I've had to remove plenty of ticks from my dog, and a few from people and this tool is invaluable.
