Leaving America is surprisingly easy. It will SEEM hard, and stressful, and you'll be panicked, and you will panic and bring FAR too many things - and many stupid things - and then you'll get there, and ... shit will just work out.
Turns out Europeans are REALLY nice. Everywhere. Especially if you aren't a tourist, but someone who has come to live there. They want to make sure that you have the absolute best experience.
Six months will pass in a blink. You will not believe the STUPID things you brought with you, nor will you believe how incredibly easy and efficient it is to live in the EU.
Champion decision. I hope they see you as valuable, and offer you the position(s).
