There is no harm in cultivating habits so long as they are not injurious. Indeed, most of us are little more than bundle of habits. Take away our habits and the residuum would hardly be worth bothering about. We could not get on without them. They simplify the mechanism of life. They enable us to do a multitude of things automatically, which, if we had to give fresh and original thought to them each time, would make existence an impossible confusion.
The author suggests that habits
(a) tend to make our lives difficult
(b) add precision to our lives
(c) make it easier for us to live
(d) tend to mechanize our lives
