Picture 2 vases sitting on a side table. The first vase is full of things that we enjoy in life-money, clothes, cars, food , toys, whatever else is important to you. But even with all these things there is emptiness, spaces where all these worldly things can never fill. Now look at the second vase- picture it full of precious water. This is the living water that fills every microspace of that vessel. It will continue to push out all the air until it completely fills the space. This is the Holy Spirit that will fill all those empty places in your life and leave you satisfied. All you have to do is ask.
