never looked into telekenisis [though sometimes i think really loud while staring at someone in hopes they can tell what i'm thinking lol] couple basic things you could do to strengthen your psychic skills would be to make prediction.
each day, before you leave for the day, concentration and try to make 3 predictions about your day. don't go with 'go to school' something like 'pop quiz in math' things that are a part of your routine don't really count as using your clairvoyant abilities. while meditating, or concentrating, you should see, hear, or feel something.
another thing you could try is take a deck of playing card and try to picture/feel what card it is. start simply with red or black, then move on to suit, face card or number, and finally the whole card.
People could teach you how to develop your intuitive senses and psychical abilities. ''Being' psychic is just using your intuition and ability to read and manifest energy consciously. We are all basically 'psychic'. As for PK, I suggest you looking into parapsychology and learn more about it and how it works before attempting it. Don't get frustrated cause you won't learn it in 1 2 3. Not all the time. Mostly after months or even a year(s). And also try qigong or yoga. And attempt astral projection so that you can get used to the vibrational state. That's PK. If you want to know more technique on this ability or other abilities you can search them on the internet or you're free to mail me as well. Farewell.
