Because of how the German school system is build (Hauptschule, Realschule, Gymnasium) and me migrating to Germany at 11 years of age without the knowledge of the German language, I had to do it differently and attend something like Gymnasium as an adult after my first vocational training (to become a heating engineer) and because of life happening and me once again migrating to another country (Sweden) without the knowledge of the language, I started university when I was 30.
Everyone else was about 20, partying and drinking, and I was studying 100% and working 50%. It was kind of hard and I'm about 10 years late with my life (compared to everyone else at work) but I finally feel that I am doing something which is challenging and fun at work and I earn a lot more than before.
The only bad thing is the biological clock not stopping to match everything else ^^.
