(i) Shift your perspective! A friend once shared his go-to trick for getting out of depressive thoughts with me, let me pass it on. He said "there is no way you can be depressed once you see how wondrous the world around us is". For example, he said, take a look at the most mundane thing in your apartment. He gave an example of the piano bench in his apartment. It was plain and mass produced.
Now, he said, imagine what is going on that surface, that top veneer layer, zoom into it. Just think how many microorganisms, bacteria, dust specks, air molecules and surface atoms are interacting with each other right now. They are creating a complex and busy universe moving constantly and in perfect harmony in that microcosm of the desk surface. Isn't that wondrous?! He said he could watch his bench for hours at a time.
Now, zoom out to our galaxy and the space. The same wondrous universe is unfolding there, with us taking the place of the specks. How awesome is that?! The same wondrous universe is constantly unfolding inside our bodies. Our bodies are hosts to around 3 pounds of microorganisms and viruses living in our gut at all times. These microorganisms, the microbiome, are invaluable to our healthy digestion, immune system, and hormones. Without us even noticing they are playing a perfectly orchestrated symphony of metabolism for many decades, how magical is that? Our bodies are perfect respiratory, sexual, thinking and moving machines. We are all supermen! How can one be depressed sitting on a "lamborghini" of such a biological miracle?! Forgive me if it was a bit too graphic with the 3 pounds of bacteria, but I hope you get the point. We are magical! Once you see how magical you are you cannot be depressed or worried, trust me!
The reason we get depressed/worried is because we are letting our brains run the show. Since our society is so brain driven, we've been conditioned to identify with our brain. Whatever our brain farts out at us, we take very seriously. Our brain analyzes the shit around us and produces a verdict "I am f*cked", or compares us against the more successful peers and concludes "I am not good enough". And we, we totally take it as if it were the ultimate truth. We are not suspicious of those verdicts in the slightest. If we listen closely, those verdicts come packaged in the voices of our parents, elementary school teachers, exes, bosses or nasty colleagues. We take those at face value and get depressed, because if we are not good enough, it's not fixable or overcomeable. This is it, we are f*cked indeed.
