Writing
"My story is a good example of how one can keep going despite every failure. My career was never about always being promoted. Even now, I don't know why, but I never complain, I don't blame others, but I set goals for myself and think about the solution. When I was fired ten years ago, they argued that I didn't explain enough what I do. Could it be that they were the only ones who could not understand me? Such people, who always look for fault in others, do not learn from anything." - Katalin Karikó (Nobel Prize 2023)
