You want to self study English effectively and your goal is improving your speaking skills to become a successful communicator. It’s awesome! You have diagnosed your learning needs and formulated your learning goals.
But, the trickiest part is yet to come; taking your learning into your control by finding appropriate materials, methods, staying disciplined and motivated… Everything is up to you and it’s easy to lose the thread of how it all works!
It’s not the end of the story; now you should find a safe place or community to put your learning into intentional and meaningful practice, or your transformation would be too slow and frustrating. Because, after all, you can only improve your speaking skills by doing it and reflecting on your deficiencies, not just by studying! Finding such an opportunity is not easy and needs trials and errors.
