^^ You are mental moving from there to Mexico
You’re not the first person who’s said that
It’s the most fun I’ve ever had, and I feel incredibly lucky to have had that experience. However, it’s just not remotely sustainable: no job security, 70 hour weeks in the summer, on call in the winter 7 days per week, unable to go far from the house, etc etc.
The main advantage of the job, for me at least, was that I was able to drive the cars as I wanted. I’ve always liked driving fast, and I was aware that if I spent years doing the same thing, one day I’d probably have issues with the police or similar. I saw several colleagues come and go because they were less careful than me. There’s no fun in driving a Ferrari at 90kph on a beautiful, wide mountain road, or at 130kph on a flat, straight autoroute, and very little fun for my customers either.
No other job I could have done around there would have paid me remotely the same salary, so without that I couldn’t have stayed and enjoyed the same quality of life. The door’s always open for me if I want to come back - I got on well with my boss and ended up running the activity, so he was very sad to see me go.
I’m very happy where I am now, but never say never
