But how can you (be happy to) come home without having been away? Maybe a lot of people need to have been out to try and experience things, only to return home a bit wiser and calmer. Ideally you'd try many things in life when young and restless, and then let old age and wisdom decide what to prioritise (if life has given you the freedom of that choice).
