    Identifying something that needs doing, especially when you have no idea how to do it, is a bold skill.

    Too often have I seen engineers be reluctant to open an issue because they don’t know how to implement it, technically. I still do it, myself. If you need it then you’ll find a way.

    The converse is also true: losing focus by filing tasks and procrastinating on features because you know how to build them, not because you actually need them to move your business / project forward.
