I am always thinking that I'm never doing anything well enough. And I'm always comparing myself to "successful and smart" strangers from the internet, who (in my head) do everything nearly perfectly and are very valuable people (I don't actually know them, I just follow them on Twitter and sometimes they're people I find through Linkedin or blogs etc).

I am also seeking validation, and my thoughts are like: "oh these people are doing X thing, and I wanted to do X thing too, then now I can do it without feeling guilty" or the contrary: "I want to do Y thing, but these people would consider Y thing a waste of time and not worth it, I might not do it then"

How do I stop feeling like this all the time? Any advice please?

**Examples:**

1. I enjoy playing video games after working/studying, I have fun playing some of them. However I feel guilty because instead of playing I could be reading books from which to gain knowledge (which I already do in fact, but not all the time, I have other interests too). But I often stalk the social media profiles of these people (Twitter, Steam...) and if I see that they are also playing video games then I don't feel so guilty, I feel like I can enjoy them and that I'm not wasting my time being a worthless person. I really feel relieved when I see that these people also play video games, like if I needed their permission or something.
2. I feel good when I identify flaws in these people. I feel like "ha! you're not perfect! i've just noticed some flaws of yours!" and then I feel better about myself because I acknowledge that I'm not the only imperfect person.

I know that people only post online the good parts about themselves, but still. I know that all of this is nuts and that I shouldn't feel like this because it's silly, but I can't get to do it. I'm always coming back to this behaviour. Any advice? (If your advice is that I stop using Twitter, that's a good advice and I already tried it, but I came back to it because I gain very useful information about the fields that interest me, from following people that work on those fields. So stopping using Twitter would be more of a loss because I would stop communication with many information that interest me.)
