I feel that the most successful people are the ones who can focus the bulk of their attention on the task at hand. An unwavering attention to what matters most. A driving force towards that pot of gold at the ned of the rainbow.
Those whose interests frequently shift, they struggle more. They may work as hard, or harder, than those with a singular vision, but being spread to then, their dreams may never come to fruition.

As someone who’s personally going through a distraction crisis, I can attest to this. I should really listen to the likes of Johann Hari and Nir Eyal and pay more attention (heh) to my… well… attention. Anyway, thanks for this post!
