Ignoring is easy if you have something important to focus your attention on. The ignoring just happens automatically. Like, given 1000 things, if you focus on 1 you automatically ignore 999. But if you don't have something to focus your attention on then its gets tricky. This is where "habitually focused" people have an advantage. (otoh, being habitually focused can be bad too. You might ignore the 999 so long that you forget it's there.)
