Hi Valérie,
First, welcome to Steemit. I am a new joiner myself and am quite excited.
Second, what an incredibly brave and wonderful thing to do. It's sometimes hard to follow your dreams due to fear and other factors, but it is great that you are setting off on a journey of a lifetime.
I once followed a guy on YouTube who decided to do something similar. He ended up travelling to every continent on earth and having amazing experiences. I am sure you are about to have the time of your life and we are delighted to follow you along on Steemit.
