1. When doing ANYTHING, completely remove any logic and inhibition and replace it with pure, unadulterated, guttural emotion (known as "feels"). Don't worry about looking like a raving lunatic; everybody else is doing it too! In fact, the influx of rampant screaming and sobbing will actually encourage you to do likewise, since it forms a sort of mob mentality.
Example: OMMMMMG! I DON'T EVEN. GFGHFGHFGHFHJGFFF I CAN'T! I CAN'T! THE FEEEEEELSSS!!!!
2. When performing 1., be sure to add an animated gif of one of the popular shows on tumblr such as Sherlock, Attack on Titan, Doctor Who, Young Justice, Pokemon, any Pixar/Disney movie, or Avatar: The Last Airbender/Legend of Korra. The most common for emotive gifs would have to be the Tenth Doctor.
3. When posting pictures, especially of animated series, always make sure that the colours are extremely bright and over-saturated, because it makes them look 'just better'.
4. Add some closing feels and you're done! Remember to remove any filter you have whatsoever.
I hope this helps!
