If the most difficult thing stopping you from achieving your goals is your own belief in your ability to do it, you're in an exceptionally privileged position.
I think we miss the forest for the trees on HN quite a lot. The modal commenter here is most likely to be affluent with respect to their local environment and wealthy with respect to the world.
