Bad effect of using twitter

When I was addicted to writing diary, I always thought about diary. Even if I think about what I would not write in diary, I thouht like writing diary. I started writing diary in English one week ago, so I sometimes think things in English now. Talking to himself in English is reccomended for practice, but I have never tried it because I felt it's strange. Thinking like writing diary in English is easier for me.

I mostly have been using twitter over the past several years. During this time, my thought was separated by each 140 characters. However, I am able to think over 140 characters limit now.
