New travellers on the roads of knowledge are like the nouveau riche: they love to show off their recently acquired wealth/knowledge. You see them eager to debate, to prove a point, to win an argument, and to make their nascent intellect as visible as possible.
This is why you see that most of 'those who speak, do not know.'

Nouveau riche (n.)
Originally from French; are people from a low social class who have recently become very rich and like to show this publicly.

قالت لي السمراء:
ما هذي الدموع؟
واسوأ ما في الرجال البكاء
أو كلماتُ الضعف تستجدي الرثاء
تُحَطِّم في داخلي أُسطورة الكبرياء
لرجلٍ يَزعَم: لا تقهره النساء
أو يتحطم شراعُه إذا ما واجه الأنواء

قالت لي السمراء:
بربّك قل لي
أحِينَ يُحِب الرجل ينكسِر؟
أم أنّه بالحب وحدَه ينتصر

(نزار قباني)

Depression—which often culminates in burnout—follows from overexcited, overdriven, excessive self-reference that has assumed destructive traits. The exhausted, depressive achievement-subject grinds itself down, so to speak. It is tired, exhausted by itself, and at war with itself. Entirely incapable of stepping outward, of standing outside itself, of relying on the Other, on the world, it locks its jaws on itself; paradoxically, this leads the self to hollow and empty out. It wears out in a rat race it runs against itself.

— The Burnout Society

R. D. Laing talked about a similar thing in his 'The Divided Self' but I can't find the exact quote

One who mourns is entirely with the beloved Other. The late-modern ego devotes the majority of libidinal energy to itself. The remaining libido is distributed and scattered among continually multiplying contacts and fleeting relationships. It proves quite easy to withdraw the weakened libido from the Other and to use it on new objects.

In the social networks [of the late-modern individual], the function of “friends” is primarily to heighten narcissism by granting attention, as consumers, to the ego exhibited as a commodity.

Have you ever noticed that you can only sleep really well when you're tired (but not very tired)?

The Fremen were supreme in that quality the ancients called "spannungsbogen" —which is the self-imposed delay between desire for a thing and the act of reaching out to grasp that thing.

— Dune, by Frank Herbert

Spannungsbogen (n.) comes from German, and it means something like "bow of suspence," like a tense bow before it shoots the arrow.

Rituals can be defined as temporal technologies for housing oneself. They turn being-in-the-world into being at home. Rituals are in time as things are in space. They stabilize life by structuring time. They give us festive spaces, so to speak, spaces we can enter in celebration.
