“Denn, um es endlich auf einmal herauszusagen, der Mensch spielt nur, wo er in voller Bedeutung des Worts Mensch ist, und er ist nur da ganz Mensch, wo er spielt.” — Friedrich Schiller

Dieses Kapitel ist meine Spielecke, wo ich Ideen und sonst so Zeug sammele, was mir über den Weg läuft und ich noch nicht so richtig weiter im Skript eingeordnet habe. Deshalb hat das hier auch keine Struktur, da mir die Gedanken eben auch noch wirr durch den Kopf geistern.

“Das Leben ist, im Detail betrachtet, eine Tragödie, aber eine Komödie in der Gesamtperspektive.” — Charlie Chaplin

“We must all suffer one of two things: the pain of discipline or the pain of regret. Discipline weighs ounces, but regret weighs tons. Every day, you are choosing which one you will carry” — Jim Rohn

“The days can be easy if the years are consistent. You can write a book or get in shape or code a piece of software in 30 minutes per day. But the key is you can’t miss a bunch of days.” — James Clear

“Der Sinn des Lebens besteht darin, deine Gabe zu finden. Der Zweck des Lebens ist, sie zu verschenken.” — Pablo Picasso

“If you are allowed one wish for your child, seriously consider wishing him or her optimism. Optimists are normally cheerful and happy, and therefore popular; they are resilient in adapting to failures and hardships, their chances of clinical depression are reduced, their immune system is stronger, they take better care of their health, they feel healthier than others and are in fact likely to live longer. Optimistic individuals play a disproportionate role in shaping our lives. Their decisions make a difference; they are the inventors, the entrepreneurs, the political and military leaders – not average people. They got to where they are by seeking challenges and taking risks. They are talented and they have been lucky, almost certainly luckier than they acknowledge… the people who have the greatest influence on the lives of others are likely to be optimistic and overconfident, and to take more risks than they realize.” — Daniel Kahneman, Thinking, Fast and Slow

“Above all, do not lose your desire to walk: every day I walk myself into a state of well-being and walk away from every illness; I have walked myself into my best thoughts, and I know of no thought so burdensome that one cannot walk away from it. Even if one were to walk for one’s health and it were constantly one station ahead—I would still say: Walk! Besides, it is also apparent that in walking one constantly gets as close to well-being as possible, even if one does not quite reach it—but by sitting still, and the more one sits still, the closer one comes to feeling ill. Health and salvation can be found only in motion… if one just keeps on walking, everything will be all right.” — Soren Kierkegaard

“Numerical quantities focus on expected values, graphical summaries on unexpected values.” — John Tukey

“Nobody belongs anywhere, nobody exists on purpose, everybody’s going to die.” — Rick and Morty

“To celebrate the noun do the verb.” — Ryan Holiyday

“The formulation of a problem is often more essential than its solution, which may be merely a matter of mathematical or experimental skill. To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and marks real advances in science” — Albert Einstein

“The graveyard is full of ‘irreplaceable’ and important people.” — Charles De Gaulle and others

“20 years from now, the only people who will remember that you worked late are your kids.” — David Clarke on r/antiwork

“One glance at a book and you hear the voice of another person perhaps someone dead for thousands of years. Across the millennia the author is speaking clearly and silently inside your head, directly to YOU.” — Carl Sagan

“If you feel safe in the area that you’re working in, you’re not working in the right area. Always go a little further into the water than you feel you’re capable of being in. Go a little bit out of your depth, and when you don’t feel that your feet are quite touching the bottom, you’re just about in the right place to do something exciting.” – David Bowie

“(1) Alles was es schon gab, als Du geboren wurdest, ist normal und gewöhnlich. Diese Dinge werden als natürlich wahrgenommen und halten die Welt am Laufen. (2) Alles was zwischen Deinem 16ten und 36ten Lebensjahr erfunden wird ist neu, aufregend und revoltionär. Und vermutlich kannst Du in dem Bereich sogar Karriere machen. (3) Alles was nach dem 36ten Lebensjahr erfunden wird ist gegen die natürliche Ordnung der Dinge.” — Douglas Adams, Per Anhalter durch die Galaxis

“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.” — Brian Kernighan, professor at Princeton University.

“The three stages of career development are: 1. I want to be in the meeting; 2. I want to run the meeting; 3. I want to avoid meetings.” — Jay Ferro

“Freude ist ein Akt des Trotzes. Mit Freude gewinnen wir, auch wenn wir verlieren. Gut gelebt zu haben ist alles was uns bleibt, denn sterben müssen wir alle.” — Jaghatai Khan, The Lost and the Damned

“Freude ist ein Akt des Trotzes. Durch sie gewinnen wir, auch wenn wir verlieren. Denn sterben müssen wir alle und ein schönes Leben ist alles was uns bleibt.” — Jaghatai Khan, The Lost and the Damned
