Pursuing a PhD in physics, particularly in particle physics, is challenging, with a high attrition rate among those who start the journey. Many students initially interested in a PhD may change their minds or find alternative career paths. While obtaining a PhD is achievable for those with determination and math skills, securing a job in the field post-graduation is significantly more difficult. It is advisable for students to focus on their interests and academic performance rather than fixate on a specific career path too early. Gaining practical experience, such as internships, can provide valuable insights into the field and help shape future career decisions.
