Just a note for anyone reading this - I was a barrister for over ten years (afraid I did go to Oxbridge though). I was pretty successful in one of the more lucrative areas of the bar, was well respected and made a decent amount of money.
BUT
The amount of money which I made compared to my friends who went into finance, industry etc was not actually that great;
The quality of life that I had to submit to in order to produce that amount of money was abysmal;
It’s very easy when you’re starting out to overlook the lack of benefits involved in being self employed. When you’re in the middle of having children and your health takes a nosedive things look very different.
I loved my colleagues, had some wonderful times, left on the best of terms and I wish with all my heart I’d done something different straight out of university. The bar takes the best of the best, demands a huge amount of them and gives back ... not very much compared to how you could do elsewhere.
Good luck op, but do think it through.
