Most valuable skill that wasn't yet told: learn to help yourself. You won't always have a mentor, or formal education on a subject. The ability to succeed despite external support is basic. Don't fall in love with a random company, expecting reciprocation; wait for the company to show love to you. If you do an astonishing good work and the company doesn't reward you, pull back, do "normal" work, then look for another company. Most companies either show their appreciation quickly and regularly, or never.
