Which major should I choose

Hey everyone I want to become a lawyer and I have a lot of interests and I would like to learn so much . I start school in August and I’m majoring in economics right now but I want to add something to it . Right now I’m thinking of adding Business information systems but I’m also seeing accounting is a good idea or finance . Is me double majoring in economics and Business information systems with pre law concentration good . Should I add an accounting minor to that . I also plan to to get my JD and MBA. Any ideas or hints would be helpful .
