When writing philosophy, you hear from two inner voices: your creative voice and your critical voice.
The creative voice tells you to write that paper, explore that idea, get that thing finished, start that project. The creative voice wants you to be free and to move forward with philosophical inquiry.
The critical voice tells you to rethink that paper, slow down, perfect that project. The critical voice wants you to make sure you do not make a fool of yourself.
We need both voices, but I find that most philosophers are overwhelmed by their critical voice. It keeps them from writing and it also destroys their reading practice. An excessive critical voice makes you hate everything you write, and you then become resentful of others who have dared to write and publish imperfect things.
My advice to students and junior faculty: pay attention to the balance between your creative and critical voices. An excessive critical voice — falsely justified by the pursuit of excellence — might be preventing you from having a successful or enjoyable career.
