Focus is something that is often repeated and lectured to us time and time again.
Elias Guzman

I think you have an interesting topic here. Since your focus seems to be on focus, may I recommend this article written by Anthony Carr. It ponders whether an over reliance on search engines and the internet in general is costing us our attention span or if it is simply changing it. I would say the toughest part of staying focused is when a person feels their research has hit a dead end if they find another interesting topic during their research. Sometimes it can bolster the researchers topic, sometimes it can be a distraction.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
