I have handled Business English clients for 13 years now, most of whom are managers, CEOs, or founders. Learning English and speaking it well gives you a competitive advantage in your industry. I remember coaching a client who was a seasoned mechanical engineer. Despite his deep experience, applying for roles at international companies in Qatar and Dubai required proven English proficiency—at least a C1–C2 level. That is the reality of working for—or wanting to work for—global organizations. Your communication skills are an investment. While very few people choose to spend money on personal development, the reality is simple: you earn from the skills you invest in."
