* Reading, writing, and oral communication. This  That last one bullet is so important that many people can BS their way past the fact that they have no useful technical skills at all. But people who are both technically competent and can communicate well are rare, incredibly useful, and therefore expensive. Strive for that no matter what your natural inclination is. Every skill requires practice. Many short applications of a small skill are more valuable than one heavy application. Run as many commands as you can, just because you can. Read as many explanations as your patience will allow. Put some effort into writing well-formed questions in your emails. Question everything you read and everything you write.
