22. Don’t stick your eyes on the screen and play
games too much – It’s bad for your eyes.
Don’t completely rely on your mobile social
network – Go outside, meet your friends, have
a face-to-face conversation to get to know each
other more.
Don’t sell your soul to the devil – Cheating in
the exams may bring you good marks, but bad
consequences.
Keep your phone in a safe place, and watch out
for thieves!
