Second thing: you can change jobs as often as you want. I am for loyalty but you can’t know what a job will be like until you work it.
If you've had projects like this in the past you'll recognise the early warning signs (eg. hard deadline before (even rough draft) requirements are available).
You'll know it's time to start the job hunt early because there's no way it can work unless you work yourself 24/7 into the ground.
It's not about accepting defeat, it's about accepting you are worthy of something better.
Note that in this case there’s no way it can work period. The product is useless and worthless. The ring that beeps differently depending on the color of objects it hits? How much would you pay for it?
I personally know better not to judge people who are not.
A job doesn't deserve more from you than it gives you.
Today it's so incredibly common (and hiring processes are extremely strict compared to before), that most companies see having started multiple jobs as "validation" from other companies.
