I have better things to do with the spare time, like chase women........lol!

Ive done the same thing, but it was never my main motivation. Although it is fun of course! A lot of jobs in China offer so much free time it just makes sense to learn something and study too. It also has an added bonus of being a ready made excuse to get rid of Gf's when you want a bit of space!

'I cant see you today/tonight/tomorrow ... I have to study/write an essay etc'
