the most valuable learning experiences i had starting out were when someone took me under their wing. my first job was a contract for a major sporting goods company. a hired gun who also contracted but had his project delayed said, "we are going to take every case in the problem queue and work them together." this was not his job - he was happy to teach me, and boy did i learn.
at my next job, a guru who seemed to know everything from midrange to programming, netware, microsoft and telephony taught me occasional tidbits like binding a protocol to an interface in netware 3.1
if you keep your eyes open and demeanor positive and helpful, you are more likely to spot the willing to educate you. ask questions without being pushy. watch to see when they don't want to be bothered and offer to help.
