> A fool > stays awake all night > worrying about everything. > He's fatigued > when the morning comes, > and his problems remain unsolved. - A foolish thing is to worry about and waste energy on things you cannot change - The things will still be there tomorrow - So wasting time staying up and wrecking yourself for tomorrow is not a helpful course of action - Better to just go to sleep and wake rested and ready to attack the issue rather than ruining the next day out of anxious concern - *"Change the things you can, accept the things you cannot"*
