Hi Pavel, Here is a corrected version that might be helpful for you: Today I am going to talk about how to learn effectively. I used to just memorize a lot of foreign words but this was very boring and not very effective. One day I realized how I can learn English more easily: I made learning a habit. I hope this helps! Best, Frankie

Hello, Pavel, Maybe the following correction communicates what you want to say: Today, I am going to talk about how to learn a foreign language effectively. In the past, I would memorize a lot of new vocabulary words each day. This method was very boring and hardly effective. One day, I realized how I could learn English more easily by making my learning a habit.
