what do you mean? using it how? in spells, connecting with it, or making shapes with it to impress/attack people?
since your elements water, you could try a few things,
1. meditate in a bath
2. meditate near a body of water
3. meditate by a bowl of water
4. learn about potioncraft
the first three will help you connect better with your element. the fourth is a possible magical path for you to test out. potions are spells that require liquid, so you could try that. i don't know anything about kenisis, personally i don't think you can really control an element [work with it and connect with it yes]
