I find law to be so interesting and the concepts covered to be exciting to learn about and it can even apply to my life. Cases studies are probably my favourite part of the prospect of doing law since I think it's interesting to learn the behaviours others have and what leads them to do what they do. I guess it does have a lot to do with how society operates but having a job where you basically have a manual to refer to what you're doing and knowing that you could be helping innocent people is really good. Mainly I like family law/cases that impact children and is the path I'd like to pursue (or criminology). Obviously I don't yet have experience in learning much law so I don't know how valid my reasoning is.
It's weird when people choose certain careers for money... having the degree doesn't guarantee the best job in that field.
