This is in my opinion one of the easiest pitfalls of modern enterprise software development. Too often I catch myself asking people questions that I could quite easily find the answer to myself. This both devalues documentation, since it won't be used anyway, and wastes the time of the people I ask.
One of my greatest points of self improvement has been to catch myself and look at the documentation first. Then if I really can't figure ot out. Turn the question into a question that can be answered by improving the documentation.
I'm nowhere near perfect at it, in a moment of weakness I still ask questions I shouldn't have asked, but I'm proud of how often I stop myself.
They're pretty fast like that and I admire the hacker spirit. But I think they miss important nuance that a proper training (even self-) would give them.
Also, it strikes me how often people would rather ask a question on something trivial rather than read the docs or at least Google the question.
Being able to search for information is such a crucial skill
