Enjoy life - and take things easy.
Sounds fucking cheesy, I know, but it's true. I'm not a sucker for any particular drive, not career, not family nor money.
When I was young, I was travelling at rocket speed everywhere. Country to country. Client to client. I visited a large car manufacturer in Sweden. All I was busy with… was the client. The focus on the city, the walk around your hotel, it was all just a “flinch of a second”.. I didn't take time to enjoy. People asked me questions about the city, all I could tell them was the canteen of the client and the small offices they had. Anything else was confidential.
Even when my boss told me, take your girl for the 2 weeks you'll be off-sote, I'll pay for her weekend in Venice including the hotel, I still had the audacity to do work on that weekend. My girl allowed it, simply as she thought it was part of my job.
