Read and implement papers is extremely good advice. It also applies even if you have a degree. I have a BA in math but in the last 6 years have found myself in positions that usually require a phd. And that is not an option with a family and no university nearby. The ability to read academic papers and understand them and turn them into something useful is very valuable. One thing I would add is to learn how to write, as tptacek obviously has. And like the reading material, not internet comments or blog posts. Learn to write real technical reports and proposals. Many engineers, in particular software people can't write worth a lick.
