@rianvdm @simondlr loving the philosophy of this, in a way it implies getting a better overview of everything when standing on top of your various skills/interests!
nothing wrong with being interested in everything around you IMHO.
Many things have intersectional truths and patterns that you don't find if you only focus on a single subject.
I'd say to achieve true greatness you need to be able to think outside the box, which doesn't work if you only focus on the contents of the box :)
