Franklin warns against assuming that an apparently generous amount of time will remain sufficient. Tasks often take longer than expected, unforeseen difficulties arise and delays consume the margin that initially seemed comfortable. What looks like “time enough” at the beginning can therefore prove inadequate once the work is actually under way.

The saying is mainly a caution against procrastination and overconfidence in planning. It does not mean that every task should be started immediately or that careful scheduling is impossible. Franklin’s broader point is that available time tends to shrink as circumstances change, especially when action is postponed. Beginning early preserves flexibility and creates room for mistakes, interruptions or additional work. The proverb therefore encourages realistic time management rather than relying on the assumption that there will always be enough time later.
