@Divyansh91565 Chill brother, 90% of college profs are inefficient af, you can definitely do it; understand the concepts, memorise derivations and practice numericals.
I also learnt two big ahh units of Physics (deadly subject imo) in 1.5 days and scored 33/40 (hard checking).

🧠 THE NEUROSCIENCE OF READING:
📖 2 min — Prefrontal cortex activity increases, filtering out distractions.
📖 5 min — Heart rate variability improves; parasympathetic system activates.
📖 10 min — Cortisol drops by up to 68%, more than music or tea (University of Sussex study).
📖 15 min — Broca's and Wernicke's areas strengthen vocabulary retention.
📖 20 min — Neuroplasticity kicks in — new synaptic connections form.
📖 30 min — Sustained attention networks in the brain consolidate.
📖 45 min — Mirror neurons activate, deepening empathy and social cognition.
📖 60 min — Hippocampal activity improves long-term memory encoding.
📖 90 min — Default mode network engages, boosting creative thinking.
📖 2 hrs — Dopamine and serotonin release create lasting mental clarity.

@aakashgupta Imagine typing all of this and not being able to actually read the post. We’re doomed.

People keep saying "just cut sugar" without understanding what 350g per day is actually doing to the tissue of your face.
When you eat that much sugar, your pancreas is releasing massive amounts of insulin all day long. That insulin signals your kidneys to reabsorb sodium. And sodium holds water. So your face is carrying this layer of subcutaneous fluid that blurs your jawline, puffs your cheeks, swells the tissue around your eyes. You stop the sugar, the insulin drops, the sodium flushes, and within 3 to 5 days the water comes off your face. That alone changes how you look dramatically.
But there's a second thing happening that takes longer. Sugar molecules are literally bonding to the collagen and elastin in your skin through a process called glycation. These bonded structures, called AGEs, crosslink your collagen fibers so they become stiff and can't repair. Your skin loses its ability to snap back. Four months of controlled blood sugar reduces glycated collagen by 25%.
And then the Mediterranean piece. People hear "Mediterranean" and think olive oil and wine. What actually matters is the systemic inflammation drop. You go from a high-glycemic processed diet to whole foods, omega-3s from fish, walking 8,000 steps because that's just how you get around, sleeping better because your blood sugar isn't crashing at 2am. Every one of those independently lowers your inflammatory markers. TNF-alpha, IL-6, C-reactive protein. All of them come down. And your face is one of the most vascularized, inflammation-sensitive surfaces on your body.
So you're looking at this photo thinking one thing changed. Three completely separate biological systems all reversed at the same time, on the same square inches of skin.

this is what 350g sugar a day and moving to the mediterranean did to my face.

@warrie2021 nothing in the verse can change/tackle any characteristic of hollow purple (it's imaginary mass), even gojo's infinity couldn't stop it when he used it against sukuna as his final move

How is Gojo going to defeat Uro when she can literally send Blue, Red and Hollow Purple back to him?

Everyone says "think from first principles" in competitive programming, but very few explain what it actually looks like when you're stuck on a problem.
It's not any trick or formula. It's a way of thinking.
It means you stop asking "which algorithm fits here?" and instead ask "what is actually happening here?'
Let's understand this with a simple example.
Problem: You're given an array. In one operation, you can choose any element and decrease it by 1. Your goal is to make all elements equal using minimum operations.
> Most people instantly jump to ideas like sorting, greedy templates, or some known pattern. But first principles thinking starts differently.
1. You ignore everything and just observe.
2. Take a small example:
[3, 1, 2]
3. Now simulate manually.
To make all elements equal, you can only decrease values. So clearly, everything has to come down to the smallest element.
Why? Because you can't increase anything.
So our target is minimum element.
Now count:
3 -> 1 takes 2 operations
2 -> 1 takes 1 operation
Total = 3 operations.
You didn't use any fancy algorithm. You just asked:
1. What operations are allowed?
2. What is even possible?
That's first principles. To think fundamentally
Let's go one step deeper.
Consider another problem:
You're given a binary string. In one move, you can delete any adjacent pair "01". What's the maximum number of deletions?
Now instead of guessing "stack?', "greedy?", pause.
Try small cases:
"01" -> 1
"0011" -> try manually
Remove middle -> "01" -> 1 more -> total 2
Now observe:
Every deletion removes one '0' and one '1'.
So the total deletions can never exceed:
min(count of 0s, count of 1s)
That:s it.
You didn't derive this from memory. You discovered it.
This is the real difference.
Average approach:
'Which topic is this? Have I seen this before?"
First principles approach:
"What must always be true here?"
Another important habit is asking extreme questions:
1. What if n = 1?
2. What if all values are same?
3. What if operations are applied infinitely?
These questions expose constraints and invariants faster than any template.
Also, Please for the God's sake don't rush coding.
The biggest mistake in contests is forcing a known approach too early.
You see something slightly similar to a DP problem -> you start writing DP.
You see a graph -> you start BFS/DFS.
But first principles thinking says:
"Understand first. Code later."
Spend time breaking the problem. Write examples. Find patterns. Only then translate into code.
At the end of the day, first principles thinking is simple:
- Strip the problem.
- Understand the rules.
- Observe small cases.
- Find what must always hold.
- Build the solution from zero.
Do this consistently, and you'll notice something:
You will stop fearing new problems.
Because no matter how unfamiliar they look, you know how to start.
