Has anyone attempted/succeeded in changing their career trajectory from Law to a completely different stream like finance, marketing, or anything other than law at the age of 25 to 30+? I don't see myself sticking around in this field (corp) for too long and am considering a change because I'm not happy/satisfied even working at a T1 because I feel like I'm not cut out for this. Not a day has gone by without me feeling anxious or unhappy and it's definitely taking a toll on me.

30 is not old. Its fine.

I believe you must have saved enough for an MBA abroad. Ace GMAT and simply get an MBA?

CAT is not worth it at that age. The cohort is mostly filled with young adults. You will have a good experience abroad. ATB.

You must attempt to change before 28 atleast. Imagine giving up a well paid job to foray into new areas and being unsure as to what will happen
