Try not to become a man of success, but rather try to become a man of value.
Throughout the centuries there were men who took first steps down new roads armed with nothing but their own vision.
All we have to decide is what to do with the time that is given us.
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.
The people who are crazy enough to think they can change the world are the ones who do.
No tree becomes rooted and sturdy unless many a wind assails it.
Wildness is essential.
There are treasures beyond imagination in the simplest things, if we care to look closely.
If everything seems under control, you’re not going fast enough.
Your boos mean nothing, I’ve seen what makes you cheer.
Today’s goals: Coffee and kindness. Maybe two coffees, and then kindness.
Fix the cause, not the symptom.
All big things, come from small beginnings.
Experience is what you get when you didn’t get what you wanted.
Create to gain power. Consume to give it away.
I design software. Complex interfaces are my jam.
I have no special talent. I am only passionately curious.
There’s no shortage of remarkable ideas, what’s missing is the will to execute them.
When building a team, my goal has always been to assemble the smartest people I can find, articulate the challenge, and then get out of their way and let them run.
You can run but you’ll only die tired.
The world runs on UTC. The rest is just local confusion.
Every day is an opportunity to learn and grow; I’m proud to be part of this journey!
