Time flies

I've recently realized how quickly time actually goes. I step back and realize that I'm 33 and a real adult with a mortgage, career, and responsibilities. Where the hell does the time go. I can remember vividly what it was like 7 years ago and I often wonder how I got here. Some say its not good or healthy to live in the past or to consider "regret" but I really wonder what the hell I've done with myself and how the hell I got here....
