I know here are many young readers who want to become a physicists. My best advice is GET Computer Science degree on top of your physics degree! Also, data science degree would be good. In my group (I work for Yale university project), most people have 2-3 degrees mentioned above. Although I am a theorist, I have to use data science tools every day to perform analysis and build models. We have a lot of data from different experiments and you have to know python, jupyter notebooks, pandas, and machine learning! Please learn all of them asap if you want to become a physicist. Today, I started my data science master degree btw (on top of upcoming physics PhD).
