I find the incredibly involved deception of WWII fascinating. See also Operation Mincemeat[0], where the British Army dressed the corpse of a Welsh homeless person as an officer of the Royal Marines, gave it a number of fake documents, and dumped it in the ocean off Spain to deceive the Germans about the invasion of Sicily.
Fun fact: most Swedes are covered by unemployment insurance, which gives you 70-80% of the income from your last job for a year.[1] I imagine this helps, as it's not only a safety net if your startup tanks, but also a runway for starting risky ventures.
It's a good point, though they did also measure how time-stressed people felt. People who felt time-poor but didn't buy time-saving services had poorer life satisfaction. If you were time stressed and bought the services, you were protected from some of the negative effects.
"In contrast, for respondents who spent money on time-saving purchases (n = 804), the negative effect of time pressure on life satisfaction was relatively weak, B = −0.03, Z = 1.46, P = 0.144, 95% CI (−0.08, 0.01). These results suggest that using money to buy time indeed buffers people from the negative effects of time stress on well-being."
My personal definition is that a programmer is someone who can write a computer program, and a developer is someone who writes computer programs for money. So you're a programmer, but not a developer. In the same way that you might be called a woodworker, but not a carpenter.
