a.k.a. wear blinkers
to be ignorant or restricted in
sight,
as if wearing blinkers or blinkers
blinkers are devices use to restrict the sight of
horses
You're never gonna be content if you
don't try, try to see outside your line
There you
go, you did it again!
You act as if there's a blinder on your eyes

only horses wear blinders, dude
