To be honest Eduvigis, I would suggest you to do computer science/computer programming. I firmly believe the future belongs to these people who work in technology companies like Google, Amazon, etc.
Not to discourage you or anything but a lot of jobs would be replaced by artificial intelligence in the future. This includes finance and law. JPMorgan has just reduced 400,000 lawyer billable hours by using technology to automate the contract drafting process. All that is required of a lawyer now in some cases is a sign off. This means the world has significant less need of lawyers. If you actually want to be a lawyer in the future, you would have to be extremely good at your job, same as finance. On the other hand, the future will see computer programmers coding and building new AIs and technology to replace humans.
