To be successful in any field, you need to know how to provide value! Every organization has problems that need to be solved. You need to be able to solve those problems with whatever tools you find interesting. With Design Thinking you can speak the language of the customer, with Data Science you can speak the language of Artificial Intelligence and Machine Learning, and with Economics you can speak the language of Value Creation for a business. Mastering these fields will prepare you for about anything, no matter what is thrown at you! In Design thinking, you need to be creative and enjoy trying and failing again and again. Great Data Scientists aren't afraid to fail and infact if you aren't failing enough, you should be scared. You have to be willing to experiment and doing it rapidly while letting your learnings guide you along the way. Additionally, truly understanding the needs of an organization or your customer is Step 1 to create value.
