life is f**king incredible. cows turn grass into ribeyes, trees turn sunlight into oxygen, fruits and coconuts, water falls from the sky and dogs exist. we get to do literally anything we want with our life, fall in love with someone who was a stranger and somehow sex with them makes new life forms. God is real, magic exists, manifestation works, and love always finds a way. dont fall for the doomer shit. we live in a magical dreamscape, dont waste it.

A massive advantage in life: Being a pleasure to deal with. Kind when others aren’t. Calm when things go sideways. Reliable under pressure. Intelligence alone is overrated. Be someone who lightens the load for folks around them. People value people who make their lives easier.

Major cheat code for life: Be patient with yourself when you’re trying to become someone you’ve never been. You’ll feel lost, unsure, and tempted to quit. Don't. Change feels chaotic because your old self is fighting for survival. Expect it to be a battle. But also expect to win.

Happiness is having better problems. Success is having better failures. Discipline is having better addictions.

Shouldn't this be default in #rubyonrails? I always do this in every app, am I missing something obvious?

Time flies, and half-birthdays arrive. Get 40% off my Practical Object-Oriented Design I (POOD-I) course (with free study groups!) and the 99 Bottles of OOP book through Dec 13th. 50% of profits go to Habitat for Humanity.  Let's build someone a house. sandimetz.com/birthday

Unfortunately we only started tracking time for our upgrade projects around 2018 (even though we have been upgrading Ruby/Rails since 2012) Since 2018 we have collectively invested more than 20,000 developer hours in Ruby/Rails upgrade projects at @FastRubyIO #UpgradeRails

One of the clearest signs of intelligence is being interested in other people’s perspectives. 95% of people I meet aren’t. Crazy.

TIL Git now has a `git stash --staged` flag to only stash staged changes. I’ve wanted this for a long time. stackoverflow.com/a/70231955…

Programming tip: Try to use as few conditionals as possible. They often make code harder to understand.

🔥 Format large numbers in your JavaScript with numeric separators. const milly = 1_000_000; This doesn't affect how the number works or is displayed - just helpful for reading large values quickly.
