Ever visit a website where every available space is occupied by text, pictures, scrolling thingees and flashing pop-ups? Nine-to-one, you backed right on out of there.
Website owners often make the mistake of leaving no margins. What if book publishers did that? If the print went right to the edges of the page, the reader might have a similar reaction as the website visitor, above. The eye needs somewhere to rest.
Why, then, do we think we can cram our lives full and still function? If you know just what I mean here, it's time to take your life back. Ditch everything that goes "blinkee" but has no substance and let yourself have the rest you need.
