What did the speaker do for a living?

I am living in a small village in the country. My wife and I run a village shop. We have a very peaceful life, some boring I say. But we love it. We know all the people in the village. They have plenty of time to stop and chat. I have plenty of time for my hobbies too--gardening, fishing, walking in the country side. I love the outdoor life. It wasn’t always like this though I used to have a really stressful job, working so late in the office every evening. I often bring work home at the weekends. The advertising world is very competitive. And when I look back, I can’t imagine how I stood it. I have no private life at all. No time for the really important things in life.  Because of the pressure of the job, I used to smoke and drink too much. The crisis came when my wife left me. She complaint that she never saw me and I had no time for family life. This made me realize what is really important to me. I talked things through with her and decided to get back together and started a new and better life together. I gave up tobacco and alcohol and searched for new hobbies. Now I am afraid of looking back since the past life seemed like a horrible dream.
