Your focus determines your experience and your experience wires your brain. In order to start the changing process, it is not enough to be mindful about the topic but we need to concentrate on that.
When we bring our focus on something, our brain starts to function more efficiently. But if we want to get deeper and create stronger results, we need to focus on our senses first as we do in meditation. Our senses are gateways to our subconscious mind which rules our behaviour and life experience by far. After getting insights from our body and understanding of what we need to do from our mind, we reach our next step of taking action.
