The best is yet to come.
The dogs have not eaten up the end of the day.
The early bird catches the worm.
The early riser gets through his business but not through early rising.
The slow horse reaches the mill.
Third time is a charm.
Time is a great healer. (Mark Twain zugeschriebene scherzhaft Ergänzung: but a lousy beautician)
Time will tell.
Totgesagte leben länger.
Unverhofft kommt oft.
