If three years ago I had known then what I know now (about the business of being an airline pilot and how my priorities in life would change), I doubt I'd be here. But I suppose that's the beauty and the curse of being human - we can't change a darn thing about what's happened. We can only live with the consequences of our choices and move on.
Don't get me wrong - I love my work, get along with the people I work with, still enjoying flying very much, look forward to making a decent living in the near future, and am optimistic that there will be opportunity to advance my career down the road.
On the other hand, I am now married, wish I spent more time at home, and hope to make additions to our family within a couple of years. Those are the things I couldn't foresee three years ago. And looking back, they would have made all the difference in my decision.
But no regrets. The next few years will be interesting for sure.
