Its really important that you practice to Visualize if you can not see the energy you create.
To Imagine and Visualize energy helps to keep your third eye to see the energy. You can rarely see energy with your physical eyes. If so, you need energy to be incredibly strong.
In order to have any energy to work with, you need to find your source.
Do physical exercise like Yoga,jog, strength training, swimming, dance etc.
It is not good to be lazy if you want to work with excess energy.
If you are using the spare energy, the exercises will wear you down and you will be weak.
