Aura reading is a fairly easy place to start, though I've never been able to see auras vividly/in their full spectrum of color. I hear they're quite beautiful, though.
For me, they're easiest to see in a mostly-dark room, with someone sitting/standing against a blank wall. You do not focus your eyes in any specific place, you just sort of gaze (more so above the head area) and let your eyes relax-- then, you'll usually see a faint outline around the person and so on. Though if you close your eyes quickly you sometimes see a flash of the color in your mind.
At one point (when I was hyper-sensitive for a short period of time, for some reason), I was able to see mine semi-clearly-- it extended throughout the entire room. It had shimmery thread-like strands stretching throughout. And although colors in the aura do fluctuate, the colors I saw in mine usually were electric blue, bright violet and gold around the edges. Then I never saw it again.
Anyway, ahem.. My psychic abilities are nowhere near developed, though. I do not practice, as I'm a very impatient person. So with me it tends to happen sporadically. But, it's my understanding that psychic ability is like a muscle that you have to continue training and building (but not exhausting it).
Though there's always the small stuff happening, for instance: Dreaming of someone you haven't seen in years and seeing them a few weeks later; typing something on the computer and hearing those same words on TV just a moment later, etc.
But as I said, yes, I believe we're all psychic. Most of us just haven't tapped into it because this ability is dormant/neglected/repressed for one reason or another. If we had all been taught to hone these abilities since early childhood, it might be different.
