Lie with the lamb, and rise with the bird.
Note: This is reminiscent of the English language proverb “Early to bed and early to rise makes a man healthy, wealthy and wise”. One obvious difference, however, is that the seanfhocal only gives advice on when to sleep, but does not go on to say what the benefits will be (such as health, wealth and wisdom). Perhaps this is indicative of a lack of conviction about the true value of the advice. The Irish reputation for enjoying the benefits of late night revelry certainly runs contrary to the dour advice offered in this seanfhocal.
