Govern your Life altogether by Measures , and Rules : And if every Action goes its due lengths, and holds up to opportunity, rest contented : Now no Mortal can hinder you from putting your Affairs in this condition. But may not some Obstacle without interpose ? No: Not so far as to prevent your Acting like a Man of Probity and Prudence. For all that, my Motions may be check'd, and my Design balk'd : 'Tis no matter for that. As long as you are easie under the Obstruction, and pass on smoothly to what comes next; This Behaviour is as good as going thorough, and serves your Improvement, as well as Success.
