Now, more specifically, here are some ways to go about learning English :
Have a reason for learning the language! What is your motivation? Write down what you will gain from learning this language. It could be intrinsic (internal) or extrinsic (external) motivators. For example, the joy of communicating with others or making more money at work.
Have an overall goal. Then, carve this large goal (perhaps fluency) into smaller goals (A1, A2, etc...).
Assess your current ability. Where are you now and where can you go? You are capable of anything~
Find resources! Don't worry too much about what you use as long as it's not giving you incorrect information, is not too confusing, or is not your style. You'll figure out what's best for you over time, through trial and error. A good dictionary and grammar book will go a long way. Also, try getting some children's books in English. You can practice reading and learn new words. They may also come with CDs.
Learn some general information about how language works. Understand the basics of the grammar of your language and the parts of speech and then compare and contrast to English. In Spanish, the adjective follows the verb. In English, the adjective comes before the verb.
Learn the different sounds and script - in other words, the *written alphabet and pronunciation of various sounds, letters, and letter combinations*. English is very irregular in spelling, and pronouncing an unfamiliar word can be challenging. You just need time and practice. Spelling and reading unfamiliar words is a challenge for many native speakers as well.
More advanced elements of natural speech (pitch, stress, intonation, rhythm) will come gradually as you learn and can be studied more in depth once you are more proficient in the language.
