The grass is always greener?

I received today a call from a headhunter with a really interesting job opportunity.
Location: back in the country where I was before as an expat, in one of the most thriving (and also competitive cities in the world).

In the last couple of months I have been thinking if I am missing my old life. The competitiveness, the speed, the night life... It was my decision to return home, over an year ago.

I guess that now that I can probably have both worlds and choose, it will be a good opportunity to find out what I really want.

It is interesting that we always seem to want what we don't have. And most of the times we never really value what we have until it is gone.
