you can do both, but generally when you take on serious tech challenges it humbles you. As an example, I used to work on Amazon S3, and that was a humbling experience. Unlike a lot of people that bounce after a year, I stuck it out for 3.5 years which is the shortest term on my c.v. Now, part of my time there was massively refactoring a critical service to maximize test coverage, reduce memory footprint, improve reliability, measure new things, make the system more durable, and introduce new features. It was exceptionally serious and difficult, and if I made any mistake then the internet would effective go down. After the fact, yes, I can be boisterous because I did serious shit without fucking up.
