English Writing Practice. Hi there, I would really appreciate it a lot if you correct my grammar mistakes or inappropriate expressions. Thanks :) Q) What is the biggest waste of time for you? My A) I think probably these days my biggest waste of time ever is using too much time with my mobile. When there is too much stuff to do and it keeps piling up, then I get easily stressed out a lot. To avoid or reduce (whatever it is) the stress, I go grab my mobile habitually and starting to do some meaningless things. For instance, reading a webtoon, spending the time to watch youtube videos or playing an old-fashioned computer game. It just takes up a lot of time and a lot of energy so that makes me regret what I have done all the time in the end. I know sticking with mobile for too long is not productive and not going to be helpful for my life and I am not even happy after all. So these days I figured it out that too much stress is the trigger of my wasting time so I am trying to reduce my stress as much as possible.
