You might thing that its really obvious, "of course i know how to differentiate my thoughts from the thing", but Socrates already said, "i only know that i know nothing", and what you think you know isnt truly right, this sort of ignorance blinds us specially when we have strong opinions about something, and then, the thing we think of, what ot actually is starts to become irrelevant, and our opinion matters more than what that thing actually is.

Got a little confusing? Let me make it simplier;

What defines a person?

Well, what defines a person is the way they think, that is directly influenced by past experience they had (note that the past experiences itself arent the person, theyre just what happened to get the person to where they are today).

That is what defines a person, logically thinking.

But its interesting, because when people compare thyselves to someone in Instagram, the someone is "perfect", flawless, but its not right. Sometimes we can only see what we want (im not saying people want to suffer), and that is the effect of negativity, of when we dont have calmness to really think, because really, people who post their happiest moments in instagram arent necessarily happy,nor does that photo tells anything (probably the person's wealth) about the person itself, because sure, they might be posting photos smilling in different contries but not the billionaire debt they are, or the emptiness they also feel and they try to fill by posting these futile things. Can you see that the person in the Photo, really isnt this "perfect" thing? Everyone has their problems, their flaws, and their own experiences, and this is something no mere photo can express, nothing can express the entirety of one's essence, but when its night, youre blaming yourself nonstop, it seems easier to believe that that person really is perfect.

This logic can also be applied to many other things, like love.

"Oh it was love at first sight", "oh i think love should be like this or like that", many things are said about love, yet, love is never truly spoken.

Love isnt "should be" or "shouldnt be", it is. We cant define it because there is something that will always vary in love; the partner, because the way i love isnt the same someone else loves, nor the way they show it and the way i express it, thats why love cant be defined, nor idealized, because that itself isnt love, its an opinion. We can say forms of showing love, but not define it formally, we can also desmystify things about love, like the "sensual" love, because "love" at first sight isnt love, its a desire so primal it speaks louder than reason, its an instict, and its not the same instict of just loving unconditionally.
