Earning more money can enable one to take financial risks for further learning, such as accepting a pay cut for a more senior position at a start-up.

Name Before Type: Why ‘age int’ Is Better Than ‘int age’ — Ben Hoyt
tl;dr: Ben advocates for placing a variable's name before its type in programming language declarations, as seen in languages like Go and Rust. The author argues that the name holds more semantic meaning and should be more prominent, enhancing code readability. Examples from Go illustrate the benefits of this approach. The author calls for future language creators to adopt the name-before-type syntax for clarity and understanding.
