72-year-old Bjarne Stroustrup invented C++ (first released in 1985). 38 years later, he gave a short interview for Honeypot.io (which calls itself "Europe's largest tech-focused job platform") offering his own advice for life: Don't overspecialize. Don't be too sure that you know the future. Be flexible, and remember that careers and jobs are a long-term thing. Too many young people think they can optimize something, and then they find they've spent a couple of years or more specializing in something that may not have been the right thing. And in the process they burn out, because they haven't spent enough time building up friendships and having a life outside computing.

I meet a lot of sort of — I don't know what you call them, "junior geeks"? — that just think that the only thing that matters is the speciality of computing — programming or AI or graphics or something like that. And — well, it isn't... And if they do nothing else, well — if you don't communicate your ideas, you can just as well do Sudoku... You have to communicate. And a lot of sort of caricature nerds forget that. They think that if they can just write the best code, they'll change the world. But you have to be able to listen. You have to be able to communicate with your would-be users and learn from them. And you have to be able to communicate your ideas to them.

So you can't just do code. You have to do something about culture and how to express ideas. I mean, I never regretted the time I spent on history and on math. Math sharpens your mind, history gives you some idea of your limitations and what's going on in the world. And so don't be too sure. Take time to have a balanced life.

And be ready for the opportunity. I mean, a broad-based education, a broad-based skill set — which is what you build up when you educate, you're basically building a portfolio of skills — means that you can take advantage of an opportunity when it comes along. You can recognize it sometimes. We have lots of opportunities. But a lot of them, we either can't take advantage of, or we don't notice. It was my fairly broad education — I've done standard computer science, I've done compilers, I've done multiple languages... I think I knew two dozen at the time. And I have done machine architecture, I've done operating systems. And that skill set turned out to be useful.
At the beginning of the video, Stroustrup jokes that it's hard to give advice — and that it's at least as difficult as it is to take advice.

Earlier this year, Bjarne also told the same site the story of how he became a programmer by mistake — misreading a word when choosing what to study afer his high school exams. Stroustrup had thought he was signing up for an applied mathematics course, which instead turned to be a class in computer science...
