Framing any and all success (maybe not what OP is doing, but a lot of people do this so it's probably worth addressing) as "sheer dumb luck" implies that you think there's a lot of things in your life that are outside your control when they really aren't. The OP may have deliberately chose that wording to convey that _in their case_, their love for computers was something they pursued completely and entirely ignorant of it being a high-demand/high-paying field. There's a lot of people that have convinced themselves that the odds of them getting a well paying job and doing better for themselves are approaching zero, for no reason other than believing that the only way to have that happen is to be born into it or to have "sheer dumb luck". That prophecy fulfills itself. There's luck involved, but it's only part of the story.
