Hy all. I will tell u my personal experience of using facebook . I used facebook for past 10 years. And now I stopped using it. Below I will tell u some of the reasons as to why I didnt liked it.
It waste whole lot of my time. It donot give me anything in return. I get unable to focus on my goals. So I just stopped it.
It contains negative content more. It brainwashes mind. And also sometimes I feel like going in my past bad memories, bcus the way fb recollects it all.
Now the facebook is more controlled my politicans for there personal benefits. And thats one of the disguisting thing .
Also added one donot learn anything meaningfull. All one see is negativity.
So, my advice will be that close fb and focus on your study.
