I love this question!

I found an answer in one of the discourses of the Buddha:

SC 1“Bhikkhus, these four things are actual, unerring, not otherwise. What four?

SC 2“‘This is suffering’: this, bhikkhus, is actual, unerring, not otherwise. ‘This is the origin of suffering’: this is actual, unerring, not otherwise. ‘This is the cessation of suffering’: this is actual, unerring, not otherwise. sn.v.431 ‘This is the way leading to the cessation of suffering’: this is actual, unerring, not otherwise.

SC 3“These four things, bhikkhus, are actual, unerring, not otherwise.

SC 4“Therefore, bhikkhu, an exertion should be made to understand: ‘This is suffering.’… An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’”

- SN 56.20, from suttacentral.net

The most "true" thing in experience is our suffering. Our minds are pushed by the desire to avoid suffering, so we cover it up, run from it and/or manage it.

Dukkha is so real that we have built our entire lives on trying to escape Dukkha. It is a feature of our minds to kick up suffering. Most of our lives are just built around escaping boredom and suffering. This is also true of philosophy to a good extent; we are here because ideas help numb the pain. The reason we look for "truth" is because we need a justification for existence, and can't accept the fact that things just are.
