"What people around you understand about your personal history."
You alone have experienced your whole life, everyone else have seen bits and pieces of it.
His/her "Yourney" are those bits and pieces of another person that you know of.
"Fastcars, lots of money - I wish I had the yourney of this celeb"
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
