Thanks MSA, I genuinely think you're just going through a bit of rut in your current role (which is surprisingly common in your mid-late 20s) once you've bedded down into a somewhat comfortable role you think "is this it for the next 40 years?" and for the first time in our lives there's no obvious answer as up to that point life' s consisted of a well trodden path of work hard at college, work hard at uni, get a well paying corporate job, etc...
When I read your post, particularly:
"It’s the type of work I do and the company culture. As cliche as it may sound, I’m looking for something bit more meaningful, something that gives me a reason to get up and work hard, a purpose. I didn’t pay much attention to this aspect when choosing a uni course, rather went for something broad and thought would help me ‘earn big bucks’"
That's such a common complaint that many solicitors have about their career, including how to break out of law into a "more meaningful" commercial career! The interactions you've had with legal work to date feel meaningful because (in a professional sense) they're new and a bit different or for your more personal interactions they directly affect your life (*everyone* gets wound up about parking tickets etc..). When legal work is the day job, that meaningfulness can feel pretty remote, and lots of legal work involves handling things and arguing points that your clients arn't particularly interested in. Particularly as a junior lawyer the reality of the day job is preparing schedules of documents, circulating documents for signing, arguing with opposing counsel over the same legal point you've negotiated many times before that the client isn't interested in, on a document they will never read, reviewing pages and pages of due diligence information simply to confirm no red flags, often for clients that are very uninterested in what you have to say and just want the transaction sorted or the dispute resolved.
Don't get me wrong, I think being a solicitor can be a great career, I'm c12 years qualified, work in a senior legal role I hugely enjoy and don't see that changing anytime soon. I went through a very similar crisis of faith earlier in my career as a corporate lawyer - I didn't enjoy it, didn't find it meaningful, was it for me? The big change I made was to move from private practice to working as a lawyer in an industry that I cared about (Renewable Energy) and that change has made my work feel very meaningful.
So, what's my advice? It *might* be that a total career change is the right decision for you, but law isn't a golden ticket to a meaningful career, in that sense it's just like any other job, some people find it meaningful, most don't - and there's plenty of boring stuff along the way. It's a big expensive gamble to retain and you will struggle greatly with a 2.2 to find a training contract. I'd recommend looking at what you can do with all, or some, of your current skills to move into a industry sector that you care about. I don't know exactly what a business coach does, but it sounds like the sort of useful generalist commercial/ops role that's applicable to lots of companies, in lots of industries, with various transferable skills (ditto an economics degree indicates you have some solid commercial financial and market understanding behind you) If you're working in an sector that you care about, I think you'll find more of the meaningfulness you want, and be able to advantage of the skills you've gained already in your career.
