You can develop psychic abilities by developing yourself as a psychic first.
Psychic abilities are not just something you can learn and memorize; psychic abilities and their development is a natural extension of psychic development.
How well you know yourself determines your limits as a psychic. Within those limits, you can form and develop psychic abilities however you chose.
It is important to note that for a psychic, psychic abilities are nothing too special - they come naturally and with ease. Only non-psychics see psychic abilities as special, mostly because they cannot do it.
In order to develop psychic abilities try to overcome your present boundaries and find new, more elegant solutions to your problems and difficulties.
Do this continually and you will find out more about how to develop psychic abilities within yourself.
