Being a good developer means to be inquisitive, curious and pragmatic. Never religious. Never dogmatic. Curious means that we should be eager to learn about all the things mentioned above and many many more. Inquisitive means that we should investigate and question all the things we learn. Pragmatic means that we should choose the right tools, being technologies, methodologies or techniques, for the job.

Timely reminder — there is no silver bullet or “one size fits all” methodology for tackling every software project.
