Your grandma’s advice sounds old right up until the exact day you need it.

Advice ages strangely. Most of what older relatives say sounds dated because the examples are dated, while the thing underneath is about people, and people have not changed much in eighty years. You cannot use it when you hear it, because you have no situation to put it in yet. Then one day the situation arrives and the sentence comes back word for word.

Collect it now even though it is useless now. Ask your grandmother what she would do about something specific you are facing, and write the answer down rather than trusting it to memory. Ask while there is time, without making it a solemn occasion.
