`` No better burden bears any man than much wisdom , '' she quoted one day from the old Eddas -- probably without knowing the source . `` I know , if any one does , what lack of money means , but I want you rather to have learning than wealth . Then , when the whole world is listening to you with bated breath , I shall walk across North Bridge resting on your arm , and I shall be repaid for all that my own life has not brought me . We shall walk arm in arm , you and I , at four o'clock , when the King goes for a walk , too , and all Stockholm is there to see ... . Will you do that , Keith ? '' `` Of course , '' he cried , his eyes shining . But sometimes she was helpless in the grip of one of her depressed moods , and then days might go by without a lesson .
