You know, I think the life of an adventurer might be compared to that of a soldier during a war. Before he enlisted, he might have had all sorts of high-flying plans for his future career.
But once he is in the middle of it, his main concern will switch to the question:
"How am I going to survive this &%!$ ?"
If he survives the war, he will come out of it changed - but in ways which he didn't expect at all. And the same is probably true for adventurers - to most of them, "career planning" is a luxury.
