I know from hard experience that knowing everything is impossible. I had that ambition as a youth. I began to learn it wasn't going to work when I was accepted to Caltech. HOWEVER Einstein claimed that we use only ten percent of our brains. Many if not most folks who hear that get the idea that they should try harder to study the things they already know. Most of us are computer programmers; perhaps we should learn new languages or tools or some other aspect of programming - if you do gui maybe you should learn kernel programming. My take is that we will use our brains more completely if we learn a bunch of completely unrelated things. My degree is in physics, I work as a coder and I compose for and play the piano. When I was in high school I sang and danced in the theater but not being such a great actor I took up set construction, eventually took it over completely.
