New generation

Everyone has a lot of issues to resolve!
It is impossible to find someone with a perfect life..
For this generation, even if they have everything, they're always lacking something.
If I look back at the past, my grandparents had nothing compared with what I have, but what they had gave them much more satisfaction.
Why is that? 
Could  the evolution of new technologies and mass media without any controls be one cause of the discontentment?
What should we expect from the future?

Ben fatto, Samuele - pochi errori!

Well done, this is mostly well-written! There's just a few grammar mistakes that I've highlighted in yellow, and some small issues with your punctuation. But this is great overall!

I would also like to say that I agree with what you are saying. No one is perfect - we have to make the most of what we have and find enjoyment in our surroundings.

THAT'S LIFE!

We all have issues but to strive for perfection we need to change our attitude and come to the realisation that we can have anything we want in this world by positive thinking and waking up each morning to a beautiful day.  The ability to notice the beauty around us and to care and share is the secret to a perfect life.

Humility is the key.  Appreciating little things and most importantly recognising one's own spirituality by looking forward and relying on the universe to provide everything we need just by asking.  Getting back to nature and living simply.  Don' worry!
