I can see myself “from the side.” I have my eyes open and typing on laptop but I can also simultaneously see myself in front of me. This is easier to do with eyes closed, is a trainable skill, and is quite hard. The reason this is useful is that it lets you dissociate from your own emotions and ego. You can say to yourself “why is that guy sitting over there annoyed about some work bullshit? He knows very well that various bullshit happens all the time, it is just a regular day.”
… bodily sensations [link]. Once they manifest, they are reinforced by loops of thoughts about them. So when you want to easily get rid of an emotion (e.g. loneliness or anger or self-doubt) you can sit down, find that emotion in your body, and pay close attention to it. This breaks the rumination cycle (because you aren’t thinking) and reinforces your self-awareness (because you find emotion-driving bodily sensations => understand that your self-doubt is merely an itch). I can dismiss negative emotions in 30 sec — 5 min. They just vanish.
The world is full of people who are waiting to give you love and compassion. Seek them out, enjoy them, and celebrate them. Don’t waste your life being stuck with people with whom you’re not compatible, with whom you don’t mesh.
