Good topic,

ESD control is a practice too few of us take seriously IMO .

I always use ESD mats at my workbench, connected to ground, through a 1 Meg resistor. I also ground my soldering iron, and use anti-static storage as well.

Here's some additional info to Guenther's and Mike's posts.

It is always wise to connect to ground through a resistor; for safety, 1 MegOhm is an industry standard for grounding a wrist strap. 

Most people can't feel an ESD discharge of less than 2000-4000 Volts, and a charge buildup can exceed 20,000-30,000 Volts. Keep in mind many components can be damaged by less than 100 V. This is why safe ESD practice and electronics go hand-in-hand

Parts that are damaged by ESD may degrade slowly, and fail at a much later date.

60-90% of part failure in consumer electronics is caused by ESD, and 70% of these failures are caused by people who aren't using ESD protection.

Don't forget ESD when storing parts; use anti-static bags, containers, foam etc. It's always best to "double insulate" components whenever possible. For example ICs in an ESD safe storage tube, can be placed in an anti-static bag.
