Ok, first things first. Search yourself and know your limitations. (Yes, I am psychic, yes I've done all I'm about to say)

    Next do some research on your abilities. If you can sense things before they happen, you "see" things, you feel things most people wouldn't, you hear things, etc. Do a LOT of research. When you've done your homework, move onto the next step.

    The most important thing you can do as a gifted person is to learn to protect your mind. Look up "grounding and protection" go to a Psychic website or Forum ( I know a really good one, message me and I'll give you the link)
     You absolutely MUST NOT move on to the next step until you have at least the basics down.

     Next start working the gifts you have. Use them (but don't over-use, you'll tire yourself out) get to know them, their bounderies and limitations. Once you have these down, use them regularly. When you are comfortable with them, move to the next step.

       Then, you are comfortable with it, start pushing your bounderies/limitations. Or you can explore yourself more to see if you have any hidden or dormant talents. With either, be careful not to push yourself to muc or you WILL become mentally and physically exhausted.

      For those of you who wish to be/are Withces or Wiccans, find a good Coven near you that will let you experience what it's like before you decide. For those who are Spiritualists or just wish to develop themselves, find or create your own Circle. A Circle is where you meet to have group prayer or mediations, maybe healings or readings.

      It is important to note that not all people have the same or can achieve the same abilities. That's also why it's important to "Know Thyself" and your bounderies and limitations. :) Also, please note that all these steps take time and patience, just like growing a garden from seeds.
