About me: I'm =~ 40 years old, not a newbie and neither a senior. Senior developer, trader or what else. I laugh in the face of 22 years old "senior developers" and tell them "When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21, I was astonished at how much the old man had learned in seven years." (Mark Twain). Most of them (everyone of them so far) doesn't understand what I'm talking about, which is weird since I did when I was their age and albeit it doubled since, nothing changed in my perception. A senior has seen, gone through, survived and will survive things that your teenage mind can't even imagine. So if the senior says don't rush so much over that trench, better listen to the old guy and stick your head under. At least before the attack.
