One of the things that is often said in Amazon that it's always "Day One."The intent is to never forget that underlying it all, Amazon always wants to feel like a startup. Whether this is a good thing or a bad thing I'll leave to another day.The last time I left a job was when I quit from where I was working in Cleveland, having been hired by Amazon. I took a month off to settle my affairs and get the house ready to sell. But underlying it all was the knowledge that I did have a job waiting on the other side of the country.Yesterday I was an employee of the aforementioned company.Today I'm not.I'm writing this probably at 36,000 feet above sea level on the way to another city... another city to try to buy a house and leave Seattle. This time I don't have a job waiting on the other end. And truth be told I might not really need a job in the conventional sense.For all the talk about "Day One" at Amazon, this is the first time that phrase is really resonating with me. It's more than a startup, it's the sensation of simultaneously being free, afraid, hopeful, and a whole host of other emotions all rolled into one.This feels like Day One in such a profound way right now.And I think the biggest feeling is that of excitement.
