What have I done today (15/06) Today I watched a movie called "King Arthur" on Netflix. For me, it was a good movie, at least not as great as other movies i've been watching for these days, but it was worth it. I was looking for k-dramas and j-dramas since I love these types of shows. Even chinese dramas like "Love me if you dare" is a great show that I watched some months ago. I'm watching them on Viki. It's an amazing plataform where you can watch dramas and movies from Japan, Taiwan, China and Korean. These type of contents have been helping me to improve specially my Japanese. I discovered a great channel on Youtube called "Japanese Ammo with Misa". I totally recomend it. That's a great resource to study grammar and to get a good idea of how the language works. When I want to learn a new word I type them on "tatoeba" and "weblio" to see some examples in order to understand them within different contexts. Hopefully, I'm challenging myself to get an n4 level in Japanese until December. But at the same time I will keep improving my English skills. That being said, one of the things I'm going to do is writing dailly here on Italki, study some grammar points on "engVid" and practice my pronunciation and speaking skills by using some techniques from "Speak English with Tiffani" on Youtube. Beyond that, I decided to begin with my studies in Artificial Intelligent since I want to develop intelligent programs to beneficiate the people around the world. And that will be a realitiy to all of us in the future. In order to open my mind, I'm reading articles on Medium, some books online and I'm taking classes on Udemy. I was thinking about to create a blog to share my knowledge and to put the "Feyman Technique" theory into practice to improve my explanations skills, in order to make them simple and easy to understand. Well, that's because someday I want to become a great teacher :) Now it's almost 01:20 am, I have to go to sleep right now :)

Is this sentence structure correct?: "Make my unproductive time becomes a productive time" For example: I'm going to make my unproductive time becomes a productive time, when I listen to audios in English while I clean my house.

Learning Spanish and Japanese in one month Tomorrow, I will make a challenge to myself to test some methods that I would like to apply in my languages studies. Well, at least to get a basic idea about how the language works. I'm going to use the spaced repetition system in order to memorize the most common words. Basically, for each word I will pick up some phrases on "tatoeba", "contexto reverso", "dictionary online" and even typing it on Google to get new ideas to choose the most useful and common patterns in order to use them in my daily life. I will begin to think in these languages to try to use them in my life context. For instance, I could be stopped at a bus station and think in English: I'm going to work right now, and so on. Also I could make labels and write questions on each one and next I could try to answer them just using the English language. I will create a productive time into a improductive time, where I will be reading during almost all my day to get used to the language. And obviously, I will listen a lot of videos on Youtube and find out a great serial on Netflix to watch and to enjoy the learning process at the same time. I just want to try new things and new ways to study a language. Because everything we did today, we can improve them to achieve our goals faster and we can make them be more cool to have a better learning experience.
