Althought I'm more or less confident in my English I'm not a native speaker, and I'm still pretty young to consider myself "really good" at English. I'm learning a lot of new words, slang words, sayings and such almost everyday but I feel like some of those that I've learned are being lost in the depths of the bottomless abyss that is human memory. How can I integrate those new words into my writing or even day to day talking (maybe even thinking?) so that they won't be forgotten? Is there a certain method you use and would recommend?
