He who realizes that time is the substance of life concludes, by deduction, that he will live as well as he can use the time at his disposal. Then he will realize, first of all, that he has no time at his disposal but now, and that therefore, extending the previous conclusion, he will live as well as he can use the now. The next step is the one that often discourages, and sometimes leads to suicide. The good use of the now is conditioned to means only partially controllable and always subject to the wheel of fortune. So, for some, it is possible to cling to a probable time as an ally against the more that fortune can get in the way of their objectives; but for others, who are averse to the indefinite, whose wisdom demands that they cling only to what is certain, it is unbearable to find that, for certain, there is only submission to the most immediate need.
