I'm a solicitor.
I got a 2:1 in law from a RG university, and a training contract that kicked in as soon as I'd passed my postgrad, so I've never had any sort of gap year. I worked in a law firm in the City for six years (two years of training, then another 4), and decided I wanted to move inhouse.
I found an inhouse role that felt absolutely right for me, and took a £20k pay cut to about £55k to do it (this was 15 years ago). That felt like a big gamble given that now-DH earns considerably less than I do, and we hadn't bought a house, but I did it anyway. Very quickly, the stressfree, quiet inhouse job changed as the business I worked for was preparing to be sold by its parent company, and I worked extraordinarily hard with no certainty that there'd be a job for me in the new business, to make that sale a success. I would start work at 9.45am and finish after 11pm, 5 nights a week, every week for literally years. I was 30ish, with no kids and DH never quibbled about my working hours, so I could do it.
The effort paid off, and I still work at that business - my salary is nearer £200k now, with bonus included. It can be stressful, and I still work hard, but I have two kids, one with SEN, and my role gives me enough flexibility to never miss a school play or parents' evening, and I'm a school governor too. DH works part-time from home, which means I can pull long hours as needed even though we don't have a nanny, and my parents who live 200 miles away are our primary childcare support. I don't think I have much balance, but at the moment it works for all of us.
