Commercial law for me would be one of the worst possible jobs out there.... I am not suited to it at all.
Working in a law firm (as a non-lawyer), I liked working with very clever people. They say if you are the cleverest person in the room, you are in the wrong room, and that was never the case when I worked in law firms. I often had the highest EQ in the room though (and my EQ isn't even that great).
My career in law firms has shaped me into who I am now, and I am grateful for that. I got to go to Paris, Brussels, Amsterdam, Frankfurt and New York - all of which were amazing. But I also lost a bit of myself (and mainly my confidence) at various points working in different law firms and I realised sometime after that I shouldn't have done.
And that is why I am in no rush to ever go back.
