It’s probably not the three R’s you were expecting.
Reading – you’re doing that right now (unless you absorb blog posts by osmosis) and it’s what students need to practice. It’s astonishing to me how little time students are spending reading… not just on class assignments, but also on relevant topics and the world at large.
This lack of interest shows up in assignments and in writing. Written communication skills are necessary in most walks of life. If you want to learn to write, first you need to read. I collect writers, both in printed form and on the Internet (see this page for writers I enjoy). Just as you become a better reader with practice, so too do writing skills improve with repetition (as long as you’re not typing the same stuff over and over).
Reliability… the “soft” skill. If you tell me you’re interested in starting a web design business, and then take two or three weeks to return an email, well… I can’t recommend you to any business I stumble across. If you tell me you’re unemployed and looking for work and then don’t follow up on phone messages… I wish these were anomalies, but they’re not. They’re typical.
And that is a very sad state of affairs indeed.
