A barbelled personality – optimistic about the future, but paranoid about what will prevent you from getting to the future – is vital.
Optimism is usually defined as a belief that things will go well. But that’s incomplete. Sensible optimism is a belief that the odds are in your favor, and over time things will balance out to a good outcome even if what happens in between is filled with misery. And in fact you know it will be filled with misery. You can be optimistic that the long-term growth trajectory is up and to the right, but equally sure that the road between now and then is filled with landmines, and always will be. Those two things are not mutually exclusive
""C++ is a fast language" is a ridiculous statement. It is not easy to write fast code in C++ and you need years of expertise to write code without memory issues."
