What lets you do your job and carry out your career? Well you could say your position, connections, etc. But I’m talking actual productivity, and what lets you actually do things is skills.
When it comes to skills, that’s a huge part of our career. We measure them with tests. We get certifications to show we have them. We get rated on the job or by clients. We seek them out or develop them. In short, a big part of your career is the ability to do something.
So more skills is good for you because it’s good for your career. Ehancing skills is good for you because skills are good. And so on.
Now we geeks in many ways are people with multiple careers. Sure we have what pays the bills, we also have our hobbies, and many of us have something in between. Your average highly active geek-type is probably doing two or three jobs at any time, and in many cases only one of them actually pays the bills. Sadly for some that’s “barely” pays the bills, so enhancing what we can do is even more important.
