The young people don't know how to have a network.

I'm 22 years old and i grew up connected on to the internet.

I always saw my oldest sister trying to talk with other peoples on the internet and for her it was more difficult to find a way to do that at that time.

Even thought it was difficult, she always tried. 

Nowadays, I've seen all these young peoples (not only teenagers) connected online/to the internet all the time on their smartphones or computer and they don't use that in the right way.

Mostly they just use all the tecnologys to share their opinion in an offensive way with no regrets.

If they learn how to use all the tools that we have today, it will be easier to build a network and make friends who can help you to grow up professionally.

good job with the writing, just minor mistakes.

peoples does not exist; it is always people.
