I gave advice for author's question: _How do you go from the "new clueless person at work" to "oh hey Mike, I'll need your help this afternoon"?_
My advice merely helps the author to speed up the process to get there.
In addition, I never join and plan on leaving in 1 year. In contracting, sometimes you work a month, sometimes 4 years. But you always go all in, regardless of the assignment.
