For how people feel about you thing I think empathy would be the best since you'd literally feel it. But anyways, a pleasure to help. Telepathy can be really simple. The only 2 reasons people would find it hard is: A. They're being told, or think that it's hard. B. They want to force it.
When doing most of these exercises I learned that forcing an ability results in unwanted progress. It won't do much as you would want to control it. So a basic thing to do is to sharpen your intuition. That weird voice in your head that tells you "don't go that way but the other way."? Follow it more often then you can. Not always though but often.
For telepathy a basic exercise I learned is to(for every telepathy exercise you need to have someone involved) : Have your partner think of his favorite fruit. Tell him to try mentally sending a visual image to you(he can either visualize sending it as a laser beam, or just visualize it flowing out of his mind into yours or whatever he likes). Then close your eyes and try to FEEL the image in your mind. Like the shape, smell, taste, color ect. "It's round, purple..." Him:"Yes, it was purim.". An example.
