To be a good developer, master the fundamentals of computer science—algorithms, data structures, and design patterns. Write clean, maintainable code and follow best practices. Embrace version control, testing, and documentation. Stay curious: constantly learn new technologies, languages, and tools. Communicate clearly with teammates and ask thoughtful questions. Prioritize problem-solving over memorization. Build projects that solve real problems, and contribute to open source. Be open to feedback, and review others' code constructively. Develop a growth mindset and resilience—bugs and failure are part of the process. Above all, enjoy the craft. Passion and persistence are your greatest tools in becoming great.

I would say "Every day is a school day" is good developer mantra.
Totally agree about the growth mindset part. How do you keep motivated when you're stuck on something new for days?
