Would appreciate some opinions on this opportunity!

I (20M)have a really big decision I need to think about, I may have an opportunity to work as an ATCO in NL. The country seems beautiful, everybody says quality of life is certainly above most Europe, which I care about. This position would bring me 4000-5000€ net in a couple of years after I finish the training.(from what could find disclosed)

Do you think this would be enough to live off comfortably? I would like to rent a nice apartment, and have money for a nice car(at some point in my life, of course), and also visit around when I have free time (Amsterdam, Eindhoven, Frankfurt etc) and just generally not worry about money. I dont want luxury, I just want financial freedom, such as eating out whenever and not having to worry about finances.

Also, NL just seems like such a safe country, like you’re not afraid to take midnight walks and such. Do you feel the same?
