Your worth, your value is not determined by what someone else makes.
Also, I'm a bit ignorant of this subject so forgive me if I get it wrong, but did he not go to school significantly longer for his MD than you did for yours?
I believe he also had to go through the hell that is residency, I didn't believe nurses do.
If you're envious of his salary, improve your skills, or your education. If you're happy where you are at In life, then don't let the fact that others make more than you interfere with that happiness.
No matter what you do, there will always be others who make more, one of those sad facts of life.
If someone tells you something, that something does not get repeated without asking for permission first. People don't have to say "can I tell you this in confidence?" Absolutely everything is kept in confidence.
I'm unsure why you would draw that conclusion. I don't know enough about Elon Musk to be either a fan of the man or a detractor of the man, but it is quite possible that he and I have views that intersect from time-to-time. Just as I'm guessing you and I may have views that intersect from time-to-time.
I'm also old enough to remember the Stasi and the KGB. So if it walks like a duck and quacks like a duck, I'm gonna call it a duck, and your project, if it really exists and wasn't you just blowing smoke, is exactly the kind of project those two organizations would have signed on for. Neither one of them wanted the citizens behind their Iron Curtain learning about things that were not State approved. So they actively suppressed those things and those who shared them, (cf. Aleksandr Solzhenitsyn, of whom you may have heard. If not, I encourage you to look him up).
I'm impressed you were able to convert the Oreos! 😉
