Don't. Do. It.

It is highly overrated as a career.

Essentially, entrepreneurs are strikers, bankers and corporate people are mid field while lawyers are ball keepers.

Go into something else: For e.g. Business opens a lot more doors. One of my best friends got both law and business but decided to stick to law for the "prestige". He regrets it tremendously although he is currently doing his training contract at one of the big 4 firms.

The nature of work that you do is really doglike for the first few years. It can be things as stupid as counting the numbers of pages manually in a document. If you see yourself doing such doglike work, go ahead but don't say I never warned you.
