Hi Ezzart,
If I were you I would use an another way. Since my memory is, many times, leak or insufficient easily, I let things in a natural way. I would try to use a word or statement that both interested or made a mistake as many as I could. When it come to language learning - as much as you use, as much as you become fluence.
Furthermore, no all the words you usually use in daily life. So, by letting some pass through you ear, I could not see a major drawback, you would have a space to keep some words or statements that more important to you.
Cheers,
