Meditation is always a plus. Some say to work on balancing or opening the third eye. Some would speak of empathy. Whatever it is you feel you have, practice using it. When I was really young I remember working with a few friends on crystal readings. It is good to explore any healthy form of intuition. I do not see These things as "abilities" so much as someone being able to feel others stronger or hearing messages from the universe so to speak. If you want to be technical all of it stems down to cues that your subconscious mind is picking up.
Sylviana is right. Mediation is one of the biggest pieces of magick and psychic abilities, if not the biggest. Try different places and items when you meditate. Some people are fine with just sitting in a quiet room, some people light candles, some people go outdoors. Find what works for you. Make sure you research the basics (you can check on the Articles section of this site) to find tons of other information.
Everyone got an energy on their brain and what i mean is everyone can develop psychic abilities but first you have to learn so much things before you do this things step by step but if you want to developing your psychic abilities first you have to meditate crate a place where you can relax light candles incense put music on a slow music that will help you relax and focus on it
meditation and balancing all your chakras can help, you need to rely on your intuition more. there's an exercise you could try by taking a deck of playing cards, hold each card and try to 'feel' if it's red or black [record results] as you get better you can begin to move on to what card [ace, 2, 3, king] and then the full card [8 of clubs, queen of spades] it can also be done with tarot cards, and specialised cards. divination is another way to improve your psychic abilities as you are using that part of you more than your conscious, logical mind. just don't expect to be able to move chairs and levitate with your mind.
