One of the hardest things, I found when returning home from long term travel was re-establishing my friendship circles. There was a mixture of old friends, plus new ones and other friends I was meeting along the way.
A friend of mine looked me dead in the eyes and said: "You have the most amazing life." I froze as my eyes glassed over with tears and my face started to burn. "Every time I see what you're doing your adventuring somewhere new, climbing mountains, jumping off waterfalls or hanging out at the beach." Still frozen as the lump in my throat almost blocked off my airways. I had no response....she was absolutely right.
