Thank you for your Question
Law as a profession is not that much easy task which people thinks about it.If you are very good to connect with other easily that does not make you good in the very profession. The main aim should be (Read, write, read, write , read and write more all day , every day). As per your query 60-80 hours work "official work" as corporate lawyer you must devote we also said Bailable Hours. Just like a Doctor/ lawyer profession is parallel but hard work is the same. If you move towards Litigation( situation becomes more complicated, just because of over population not of work but of law colleges, each state , city is carrying ample number of law colleges.
Moral is if you good at writing and reading and can devote yourself in law , then you have chosen a right profession.
