Brian Johnson argues your biggest obstacle isn't one big flaw but tiny habits that pile up. He uses Dave Asprey's kryptonite dust metaphor: small repeated negative actions gradually weaken you. The fix is identifying and eliminating these micro-deterrents to restore your power.

As a general philosophical concept, it's the little things that get us. It's not the huge, huge things, it's the tiny little things. And one of my favorite metaphors on this is Dave Asprey's kryptonite dust. He tells us that if you had Lex Luthor and he wanted to get Superman, he can obviously bring a big chunk of kryptonite and that will immediately drain Superman of his powers, period. But if he was really creative, what he'd do is he'd take that kryptonite chunk and he'd break it down into little tiny little pieces. He'd actually make dust out of it. Then he'd sprinkle it in Superman and Clark Kent's house and office, right? And that little bit of dust would wear away at Superman's power gradually to a point where he wouldn't know what was happening, but all of a sudden he wouldn't have the same level of strength he used to have, right? That kryptonite dust comes into our lives, those little things that we're doing are diminishing our power. So we want to identify those little things and eliminate them and get that power back, right?
