Strong writing skills in English come from practice and determination. No one is born an excellent writer. Learning to be an excellent writer in English takes a lot of time and practice. Anyone can be a good writer if they are determined enough.
Everyone has a different reason why they need to improve their writing. Maybe you need to improve your writing for work or for your English class at university. Or maybe you want to start a blog about learning English or you need to respond to emails in English for your business.
