Well, it's no secret that mobile phone takes an integral part of our life nowadays. Needless to say, teenarers use their mobile phones too much. I'm not an exception either.
In my opinion, there are both advantages and disadvantages.
The first advantage is my opportunity to connect with anyone at anytime. It's quiet simple now. My parents weren't worried about me anymore. They call me every day.
Secondly, I can call my girl/boy and have a date or just talk to. This , in its turn helps our relationship. Besides, I can send him/her a picture of the nice place or just funny picture.
Thirdly, my friends are always in touch. It's quiet convenient to make an appointment with them.
The last one is the internet. I have a modern gadget with me and it means I know the latest news in the world. Besides, I can get any necessary information what I'm interested in. Internet makes my development easily, faster and more comfortable.
Of course, there is a great disadvantage here too:
Modern gadgets take majority of time. Games and other daffy applications make people stupid. It's not enough to stare at the screen only. The world is enormous and there are lots of possibilities to travel, see other countries, meet new people and join other traditions and culture. It needs to learn and read books more. Practice any of our skills everywhere in real life not in VR. Do the best , be the best in any directions of our life, work, travel and leasure activities. Get your success by yourself first and a smartphone is a small piece of your life which will complement it.
