Change is simple, but it isn't easy.
'Everything you need, to get everywhere you need to be, is already inside you. But without a strong desire to know or learn something, we will never experience the change we so desperately say we want." -Eric Thomas
What's the number one goal of most gym goers? To lose weight and change their body. That ability to change ones body is already inside them. They have all the tools to make it happen, but do they have that strong desire? You can say you want change, you can say you want to lose "x" amount of weight, but that desire has to be there.
