I still have a lot of homework in the summer vacation. My parents promised to take me to travel when I finished writing, so I forced myself to do my homework.

I suggest you make a plan, that is, how many pages of homework you write every day and how many days you finish it.

As for the mobile phone, I don't think it's impossible to play, but to control it.

I suggest you do this and play after you finish your homework. Better limit the time.

If you want to do anything well, you must learn self-discipline
