How to learn English

First, i want to start this tutorial saying that this requires a lot of confidence to start the journey of learning english passively, and start learning english actively.
My emotional strategy to learn English is:

1. Admit that this journey is gonna be hard. Listening and Reading.
2. Trust in the process, actively push yourself to reach that goal.
3. Review yourself. Because you can take a lot of courses, readings, podcast, etc. But how can you see your progress? Measure it.
4. Do it together. Trust in the people that is in the same journey.
