I suspect Norman Foster has a lot of fun architecting. I also suspect that a great many architects are engaged to design yet another bedroom extension or garage conversion. The majority of careers have a significant downside and there is an art to finding the bit that has the best balance. Unfortunately, there is no guaranteed approach.
The OP is far from being too old to enter the commercial flying world, but any potential employer will expect to see some evidence of a passion for flying. Without the evidence, quite a few doors are unlikely to open.
To become a commercial pilot is a massive committment - £100k is often mentioned as the base financial cost and there is a huge personal effort involved as well. Get flying and get your PPL. If flying is in your blood, your neck will get stiff from looking at the sky and wondering if you can get up there today. If that's you then great, crack on.
