If youre even a little bit ambitious, you will almost always be miserable
not because youre not doing well, but because you expect a LOT from yourself and you're always in a hurry to do things
you constantly compare yourself with others (even if you know that its completely irrelevant)
wins become meh, which means even if you win you will treat it as the least acceptable possible outcome, not a reason to celebrate but a threshold that you must always pass
guilt kicks in even if you take a day off or don't open your laptop, work all day everyday and you're not satisfied either
weird place to be in

“‘You’re 25, relax… you still have plenty of time in tech.’
Sounds harmless, right? 😂
Poverty to you 👇🏿”

• Build arguably one of the most critical machines in the modern world (EUV litho to make world’s powerful chips) 😊
• Service them globally at TSMC, Intel, Samsung, Micron, IBM etc.

Most hacks today aren’t fancy smart contract bugs anymore.
They’re OpSec failures, private keys, phishing, multisig compromises, and access control.
SC Audit + OS Audit (Operational/Off-chain Security)
must become the gold standard.

sorry guys but defi will be doomed if we don't solve security

I know my soul yearns for greatness and excellence because it is capable of handling them.
I wouldn't yearn for these things if i couldn't handle them. There's absolutely nothing i cannot achieve, and conquer. As long as my soul wants to.🤍

I don’t know how to explain it further or maybe I don’t want to, but people who are successful at their careers are not the regular 9-5ers. They don’t keep the mindset of people who watch the time while they work!
That’s who this lady is!
She’s an engineer, she has worked beyond her working hours. And from what Femi has said, she has also gone an extra mile to deliver meals!
Again, a dev! While others might have foams in their mouths if you ever ask them to do such, she is doing it as a pathway to understand user behaviour that in turn helps her to build a super app!
This is not advice! There’s no moral to this story. I am not asking you to do anything. But people who want to join us at the top 20% of our careers will definitely take this as a wake up call!
NOBODY IS SUCCESSFUL IN THEIR CAREERS BY LOOKING AT THEIR 9-5 CLOCK!
Selah; this is my sermon today!

Q1 is behind us.
$140M+ lost in 5 hits. 💸
Web3 devs, stay sharp:
🔑 Key theft (Resolv/Step)
🔢 Integer Overflows (TrueBit)
📞 External calls (Matcha)
🔮 Oracle bugs (YieldBlox)
Logic is only half the battle - OpSec is the other. 🛡️🦀

Software engineering isn’t dead because we still need actual engineers to build AI systems. We need real thinkers to plan and reason about how systems should be designed, and architects who can structure solutions from a high-level design down to a low-level implementation.
Software engineering will not become obsolete now or in the future. What’s changing is that it will no longer favor people who only focus on writing code to meet deliverables. Instead, it will favor people who can think deeply, design systems, and understand trade-offs.
This is where system design becomes very important. The shift is from just “building features” to actually designing scalable, reliable systems.
AI won’t replace the need for engineers who can translate ideas into structured system designs. It can assist in implementation, but it still takes human engineers to define what should be built, why it should be built that way, and how the whole system fits together.
That’s the real value software engineering will continue to demand.

AI is shrinking the world. And that will affect everyone. When I was leaving university almost thirty years ago, the talk was all about being “computer literate’. In 2026, the talk is about being ‘AI-literate’. Software engineering may just be dead as a mass profession. You’ll probably need a higher degree of specialization and expertise to be a software engineer these days.

Your brain was built for war.
For creation.
For solving problems bigger than yourself.
But you’ve trained it to crave shortcuts.
Quick laughs.
Cheap dopamine.
Empty validation.
And now you wonder why studying feels impossible.
Why focus feels like torture.
Why consistency feels out of reach.
You don’t need motivation.
You need to rewire your brain back to its original state, hungry, sharp, disciplined.
Kill the distractions before they kill you.
