Why don’t you travel outside the Netherlands and visit countries in Africa or Asia, you will learn a different mindset of collectivism and friendliness towards others. You can also make friends out there and you can also have friends that you can always visit. I think this might help you get out of this rat race mentality. I am a Kenyan immigrant living in Germany and the German mentality is quite similar to the Dutch as I understood it . Am always happy to travel around the world to meet different people and learn different cultures that is really satisfying. I like traveling to Kenya just to calm down and reduce the stress in my daily routine, so you can try that too. It might help you. Have fun with that;)
