Impossible but you can learn other things such as nlp and other things which seem to make you possess the power of telekinesis
It's different for everybody, you could do it the first time, the second, the 400th time or never at all. Normally, it takes a few weeks of practice to move small objects. A psi wheel can be moved quite quickly for most people.
hydrokinesis is when you control the molecules in water and aquakinesis is just when you bend water
i don't know if your the avatar wants to learn all elements but its all possible,for hydrokinesis you need enhancement of science like hydrology for telekinesis physics or something like that but you know geokinesis i dont think whats geokinesis is but i think you mean terrakinesis. good luck...
If you learn Ku style Tai Chi (Yang style). This is a form of bending the water to your own will. Ku style Tai Chi is also known as "Waterbending."

Depending how quickly you pick up on the basics behind the wheel, it will take as long as you need to learn the ropes.
