1. ________
Social networking websites are growing and changing all the time. Although younger users might not stay with one site for long, they still enjoy the concept, and a lot of their daily communication with friends takes place on social media sites. They send photos, exchange news, post where they are having coffe with their friends, and share favourite music and videos. It's fun, and it makes you feel good.

2. _________
Or does it ? As Hanna Krasnova of Berlin's Humboldt University, an author of a study on social media networking, says, 'We were surprised by how many people have a negative experience from [social networking], with envy leaving them feeling lonely, frustarted or angry. If you spend too much time looking at friends' posts and pictures - with their happy graduations, wonderful holidays abroad and perfect parties - you may start to wonder what's wrong with you '.

3._________
And envy of others' perfect lives isn't the only negative aspect. Bullying, other people sharing your deepest secrest, and general embarrassment at seeing the worst photo ever of yourself posted for all the world to see, can all be bad side effects of using social media. And then there is online addiction, which leaves many people unable to switch off their devices for more than a few minutes at a time without suffering from nerves and anxiety.

4. _________
So what can you do to make sure social media remains a positive part of your life ? Probably the most important thing is to make sure you don't spend too much time focusing on your digital life. 'At the end of the day, nothing can replace face-to - face conversation and interactions', says one writer. 'It's better to get together with friends, go out for a meal, or sit and chat in person. When you're with a real person , it's much easier to understands what's going on and what your friendship really means'.

5._________
A second thing to keep in mind is that your friends on social media should be real friends, not just acquaintances. You should only 'friend' people you get on well with and look up to. In the end, just like in real life, the number of friends you have doesn't matter. It's the quality of the people close to you - even on social media - that is really important.
