Law is a lot of reading but it's all quite similar in structure (cases, statute etc...). Try reading some law text books if you can get some from a library and some statutes and case reports, it's pretty dry stuff really but, like anything, interesting if it interests you.
The subjects are quite wide as you cover a fair amount of different areas on a standard law degree. I found some more interesting (and understandable) than others. It's a very wide subject area at degree level and quite academic with quite a bit of history involved.
The LPC is very different, more intense and practically based as it's meant to prepare you for doing the actual job (it doesn't, in the slightest, more a learning base).
Practice itself, as Jayne says, it's not the gravy train people think. Yes, some lawyers do earn very good money although, like many careers, there is often a sacrifice to be made in terms of hours, life balance etc...
The larger salaries are more found in the larger firms - they are businesses so you have to earn yourself so the more money you can charge in fees, the larger the potential salary so it's more the commercial firms who pay larger salaries.
What you specialise in also makes a difference.
Noting that, as training contracts are so hard to get, you find quite a few people don't get to train in their chosen subject area, or, if they do, get a job in it afterwards so can end up doing something different. Once you are into one area it can be incredibly difficult to move as the areas are very different. People seem to lump it together but it's like, say, a teacher saying they fancy switching teaching from, say, languages to science.
Essentially, it's an office job (maybe with court/police station etc... work depending on what you do) and can be very stressful. There are areas I'd never have practiced - sitting in a local Magistrates watching bail applications put me
