Pass it on! Pay it forward!
For those of us who have children, there is great joy in showing them how things are done, teach them our skills, guide them.
For those of us who have parents, there is no way stopping them from sharing outdated stories, opinionating about our life choices, giving unwanted advise.
Forgive us our trespasses...
Adult life contains a need for passing on knowledge. It is as ingrained as breeding. Even if we don't breed, we may mentor.
There is a lot of love in this. Sharing our experiences is the opposite of "knowledge is power". With our children, we hope that they will surpass us one day; with others we hope to connect and wish for their success.
It is an important phase in our development to accept that at some point we will reach zenith in our own careers and can take genuine pleasure in the advancement of others without feeling jealous. (Americans are really good at this. They say "Good for you!" and mean it when other people are promoted or sell their company for $19B (unless it was a promotion they themselves were in line for or perhaps a competitor that was bought. Then they only say it. Even in "God's own country" there are very few saints.))
But passing on our wisdom does not have to relate to career advise. It can be practical: How to brush your teeth. How to make the perfect souffle. How to use a plane with, not against, the grain. It can be more philosophical: How to avoid unnecessary pain and trouble.
Living abroad gives us an extra outlet for passing on our experiences. We can pester the people back home and expat newbies with our stories. You can take them or leave them; we are not offended because we know that unlike our children, you need not listen politely.
But know that it is an act of love. To help you avoid unnecessary pain and trouble. And then pass it on...
