I agree with you: in all learning there must be not only theory but also practice. It's no use to handle concepts if you don't know how to use them. In my case I have had a very bad experience with English, but it's because I think I've closed myself off. Human beings are our own saboteurs. I think I've blocked a part of myself, especially when it comes to spoken English. I don't have people in my immediate environment with whom I can converse in this language and when I have been able to do so, I feel very ashamed to make a mistake and prefer to remain silent. Sometimes I've started talking to myself, but it's not the same because I need someone to listen to me and correct me, to guide me. I know that if I want to advance in the acquisition of another language, I must not remain in pure theory, I must practice, practice and practice, even if it is alone. Thank you for your advice, @whatamidoingand and @adsactly for bringing us these learning microtext.
