Just a Click of a Button

I’ve been reading about eligibility for a US Green Card. The whole lottery thing riddles me with nervousness – I never win anything. This I want to do. I have itchy feet, I’m feeling frustrated at my everyday life, I’m idling. Would going to another country for a few months a few years make a difference? Should I still and ponder if working abroad could change / influence my life at all. Should I not wonder and just click that little button? Do I register for 1 year, 2 years or 4 years? What if something monumental happens in my Sydney life? Would I still go if accepted (won) If I don’t hit that little button would I regret it and always wonder or even worse look back at my life in 40 years time over a Bridge game and regret never taking the opportunity to live my life elsewhere…
