Because life is like that, isn't it? If you thought of all the tiny things that divert your path one way or another, some good, some bad, you'd never do anything ever again. And some people don't. Some people go through life not really deciding to do much, not wanting to, always too fearful of the consequences to try something new. Of course, that in itself is also a decision.
Really, when I look back on it, I did exactly what I had set out to do. I changed my life. I woke myself up. I rediscovered passions of every variety. I forced myself to take a little time. I found a way to bring some of who I used to be into who I was.
