Just a quick observation about learning languages:
Learning English might help you reach goals and enjoy learn opportunities, but it won't change who you fundamentally are. If you're shy, English will not turn you into a social animal. If you find human behaviour confusing and you don't understand what people are doing, English will not make you wise and make you understand the motivations why people do everything.
If you buy a better hammer, that doesn't make you a better craftsman. If you buy a really expensive pair of trainers, it won't guarantee that you will finish a marathon in under three hours.
English can do a lot of things, but it won't make you radically different from the person you are today.
