We all have at least one. And we can never really escape them.
Our chains aren't necessarily physical. They might be emotional. More often than not, they're psychological. The chains that keep us bound to habits and ways of thinking that hold us back.
Those chains, in whatever form they take, will always be with us. We can continue to be constricted by them. We can try to break them. Or, we can try to loosen them so we're a bit more comfortable, a bit less restrained.
Sometimes, the third option is all we can hope to do.
