There is no doubt that loafing is the activity which people like (to do) most. However, in this increasingly stressful world, it's increasingly difficult to do. Even though it is difficult, I believe it´s important we sometimes just calm down and loaf. Our minds need that sometimes. But we can't get overdo it, because when Monday comes, it is time to work.
In "our minds need it...'' I changed to "need that", same effect and you add variety to the text. That is, I tried to leave out an "it", whenever I could.
