For non native speakers of English, what strategies work best on you to be able to speak and understand more English words?

my written english is okay, but i wouldn't be mistaken for a native speaker if i spoke. hmm, maybe if i worked at a call center, i might eventually acquire the accent?

I'm a true bilingual, I speak both Pilipino and English from a very young age, I sideline teaching coversational English to English teachers and even tutorial school owners online in another Asian cointry. Don't get me wrong, my students are the best ( better than me cause I did not study education or majored in English) in teaching grammar and written English but some confessed to me that they feel ashame when they are asked to speak or when speaking to parents of their students. My tips: - find a native speaker to converse with whenever possible. - Read, watch movies, increase your vocabulary whenever possible. Jot down words, phrases or idioms that you cannot understand and don't be shy to ask. - American English is full of expressions and idiomatic expressions that non-native speakers would find hard to understand in actual conversation so it would be advantageous to learn them.
