I started taking notice of how family and friends (who I don't consider disabled in any way) were using their computers. A good friend of mine has a hand tremor which makes it difficult to be precise with the mouse. My grandpa had difficulty seeing small text on the monitor. These were things I could and should be building for. This new awareness is what caused me to dive into website accessibility and universal design in general. And here are a few reasons for you to make it a priority as well.
