Some good hints on writing in Philosophy
It is also very profitable to start a writing/reading group with your course mates/friends, where your writings can be shared among your peers for constructive reviews. Two good heads are better than one because they provide four good eyes.

You too can start your career, though at the student level, by taking similar steps.
