Before I go to bed, I usually enjoy smart-phone-time = spend time on my smartphone

When I concentrate on it and youtube, sometimes I fell asleep in late night = sometimes I fall asleep late at night, but it is very helpful to relief my stress at work.
I enjoy chattering with my friends via discord, watching video cilps on youtube or studying while listening music.

However, there is something else that through those habits = there is something else that I have realized through those habits , I actually consider the most important. That is positive thinking and watching positive contents = content before sleep. It is really important that after taking a rest our brain starts working at the point before we sleep. So if we think about negative problems, in the morning we may wake up with unpleasant feelings. This tendency has evident from the research and I believe that.

For this reason, I try to get close to positive and funny or beneficial contents.
