Got a new challenge for myself ...
...
Learning 5 new words or expressions each day, after reading a non fiction book. I found my iPad 2 being better for that, but of course, a piece of paper and pencil will work.
Because English is my second language, finding new words is very common when reading non technical books, which is my main area or working skills.
Started with "Ghost in the Wires", really good book, by the way. Read it already. Going to read again and start writing down new vocabulary.
