Depth. Every programmer I admire has worked on their chosen field for years. You can keep flitting between languages and frameworks, but mastery ultimately comes from hankering down on one thing and advancing our collective knowledge a bit further. You can achieve mastery in any field - it can be a business domain - as mundane as a Time Tracking or a Todo list app, or it can be a technical domain - like compilers or databases or browsers. You however can't achieve mastery by consuming what others produce. Becoming an expert in CSS and its quirks is a good vocational investment, but you're no closer to a fundamental understanding of the field by just consuming an API. You should spend years working on a problem domain that interests you. Look at prettydiff (https://github.com/prettydiff/prettydiff https://github.com/prettydiff/prettydiff). It is a diff tool, a parser, a pretty printer, a minifier, all rolled into one. It is the most comprehensive publicly available tool in terms of language and dialect support in the world right now. Its code is not the most modular and new contributors might have trouble getting in, but its author has been at this problem for years, and if you called a conference for pretty-printing, he would be one among the few thousand people in the world to meaningfully participate. Consider blueimp's jQuery File Upload plugin (https://github.com/blueimp/jQuery-File-Upload https://github.com/blueimp/jQuery-File-Upload). While this isn't as foundational a work as prettydiff, the project spans seven years and a thousand commits. It solves a mundane problem, but the sheer effort that has went into it makes it a formidable solution. Consider Martin Odersky, watch Compilers are Databases (https://www.youtube.com/watch?v=WxyyJyB_Ssc https://www.youtube.com/watch?v=WxyyJyB_Ssc). He has been writing compilers for like forever. He's worked on the field for decades, and has written compilers for everything from Fortran to Java to Scala. You don't have to be a genius to be a master. You just need to go as deep into a field as you can.
