To become a good developer

For I good developer I want to become:

    Planning: getting the required information, tools and resources together;
    Designing: both high level (strategic) and detailed design during which we analyse the problem and work out how to solve it;
    Coding: actually typing in the lines of code;
    Compiling (if we are using a compiled language): running the compiler and correcting any errors until we get the program to run;
    Unit Testing: running one or more tests to check if the program is correct. While testing we sometimes have to correct errors to the design or the code and re-compile the program.
