Great inspiring article ~ thank you! I especially like the commonalities practice "Just like me, this person is..." Starting from a place of compassion makes it easier to see all the opportunity for simple acts of kindness.  

Wow, 15 years is a long time! I hope you are doing it with someone! :) My current thoughts are either
1) Continue as I am for another 2 or 3 years and then settle down somewhere for 6-9 months a year and travel for a few months a year away from my base. This would allow me to focus on building long-term relationships which is an important factor missing from my current travels other than frequent visits home and back to visit friends in other places.
2) Find someone who I could spend my life with and share my travels with.
