Depending on how worn or knicked it is, you can possibly do it yourself. If it is mostly just worn and has only very small knicks, you can do it while it is still attached to the mower by using a fine file for metal. This is a bit awkward, but can be done. File the top edge to about a 30 degree angle. Do not file the bottom of the blade.
If the blade is more than just a little worn and has some deeper knicks, you must remove it from the mower. Scrape off all dirt bulid up. Again, you can use the same sort of file and file it in the same manner. If you see any cracks near the outside ends of the blade scrap it and get a new one. A cracked blade can come apart while cutting, sending shrapnel out from under the mower, resulting in serious injury. Then you need to balance it like Niceguy says. Put it back on the mower flat side down (you'd be surprised how many people reinstall the blade upside down) and tighten it to 55 ft/lb of torque.

Take the blade off the lawn mower and use a Bench Grinder or a File to sharpen the blade.

You can sharpen it manually with a file or take it somewhere like Ace and have them do it. If you have or are thinking about buying a Dremel tool, they are great for all sorts of projects. They usually come included with a special bit and guide piece for sharpening lawn mower blades. The guide keeps the bit at the correct angle for you.

You are best off taking it to a pro, but if you decide to do it yourself you must make sure it is balanced. If it is not it will cause vibrations in your mower and may cause damage. It is fairly simple to do. When you finish sharpening the blade tie a string on the center hole and it should hang level. If it goes down on one side, you need to file off a little more material on that side so it is balanced.

I use my grinding wheel on my workbench.
First I oil the blade, then with safety goggles, I carefully hold the blade toward the grinder away from me at an angle down so the wheel is coming DOWN on the angle of the blade--opposite of sharpening the knife with a stone and oil--for safety reasons I do this. Then I use the rotary brush to get the bits off left behind.
Be careful!
