This is a list of resources on how to succeed as a PhD student and how

The Seven Habits Of Highly Effective People by
Stephen R. Covey. (Amazon)
Most PhD students need some help with managing
their time, and this only gets harder as you go along. This is the
leading book on time-management. It gives guidance on juggling
competing demands on your time, setting (and keeping!) priorities, and
the psychological dimension of time management. I've had a number of
students who found this book invaluable.
