Lovely post!! I have to reply :)

My nostalgic moments are scattered over my whole life. May it be when laying on the living room floor in a sun beam and watching the dust dance in the glow of the ray, or the star filled sky of the desert night, or the first girlfriend I was really in love with. There are many moments.
At the moment I miss the feeling I had when taking my first world travel. Wandering through the streets of Budapest alone. Taking everything in and having the freedom of experiencing the moment with no one interfering. Sitting in a Cafe in Chiang Mai with a book and observing the bustling traffic and life from the terrace (forgetting to read the book actually). No worries, peacefulness, and this lovely subtle feeling of happiness.
I think the moments that make us feel ourselves in the most human way are the ones we cherish. Feeling alive. May it be climbing on cranes, running on the beaches of Morocco, being with your girlfriend for the first time or just breathing in absolute silence. Everyday life tends to scream all sorts of necessary obscenities at us that we have to manage. Work, paying bills, etc..
Right now I am at a point where my life is completely at zero. The old life has broken away, no financial reserves, no steady home and nothing but an idea and a determination to keep going. So my nostalgia at the moment is to get to the point of feeling my human self again. And I will. In a few months time I’ll look back at the present moment and think back in nostalgia, as in those moments of complete uncertainty all your powers are called for and bring you forward to new actions, new adventures and new acquaintances. As soon as the difficulties are overcome I will look back and remember how much i felt alive. So kind of a nostalgia in the making. Unfortunately I really dig new beginnings.

And I really like nostalgia :-)
