Each of your breaths is a priceless jewel
You should structure your time, arrange your regular devotions and assign to each function a set period of time during which it is given first priority but which it does not overstep.
For if you abandon yourself to neglect and purposelessness, as cattle do, and just do anything that may occur to you at any time it happens to occur to you, most of your time will be wasted.
Your time is your life, and your life is your capital; it is the basis of your transactions [with Allah], and the means to attain to everlasting felicity, in the proximity of Allah the Exalted.
Each of your breaths is a priceless jewel, and when it passes away it never returns.”
