First, remember that if I made it, you can make it. I went to Catholic kindergarden and the role models were the nuns and the Saints. I did not have very good marks, I would never have entered Computer Science at NTNU with the marks I had in high school (50/60). But I get very good marks at the admission exam at Politecnico di Torino because I was motivated to enter that PhD program. And I met some good role models on my way.
