You should start by familiarizing yourself with basic English grammar, vocabulary, and sentence structure. You can do this by using English textbooks or online resources that provide grammar explanations and exercises.

Once you have a solid foundation in grammar, you can start practicing listening and speaking skills. You can do this by watching English movies or TV shows, listening to English podcasts or music, and engaging in conversations with native English speakers or language exchange partners.
Reading is also an important part of learning English. You can start by reading simple texts like children's books or graded readers, and gradually move on to more complex materials like newspapers, magazines, or novels.
Additionally, writing is a crucial skill to practice. You can start by writing short paragraphs or journal entries about your daily life or topics that interest you. You can also find online writing communities or language exchange partners to get feedback and improve your writing skills.
Finally, don't forget about practicing English on a regular basis. The more you expose yourself to the language and use it in different contexts, the faster you will improve. Good luck!
