I want to leave France because I lived there 23 years, and I feel trapped there, world is big and I want to experience new things.
You are right, it is hard deciding between Pittsburgh, Portland OR, Toronto, Vancouver, Canberra but I have time before I receive my passeport. My heart will decide, who knows. Thank you. Jeremy
But how is your heart going to decide if you haven't been to all those places? And spending time in each place (say 6 months) is difficult -- not to mention expensive -- I'd suggest you make a list of the things that are most important to you: weather, type of job available, cost of living, type of housing available, culture, etc. Be as specific as you can be, then try to research them for each place. Your heart might confirm your choice, but your mind should be in the lead.
Bonne chance!! Buena suerte.
