Can't tell what what part of the country you are from, but here in Florida I hardly worry at all. If I'm wearing shoes and walk across some carpet, I may touch the ground jack on my soldering station just as a good measure when I sit back down. Even if you live in a dry area prone to a lot of static, that should suffice...unless you are working on a carpeted area and shuffle your feet a lot. In that case a wrist strap might be in order.
From what I can tell, most of the parts we are using are tough as nails. I've put them in backwards, super-heated them, etc. and had no problems yet once I got things right.
