There are a number of dimensions that you should focus on in protecting your purpose. Your body is one of those important dimensions. When you are not feeling well and your body is not operating at an optimum level, it inevitably has an impact on how much you are able to deliver. When we do not look after our bodies we could be accused of being irresponsible in relation to our purpose.
We are often quite unaware of how our belief systems are influenced by various external factors, and how those beliefs may impact on our decisions and actions. Not interrogating information that we are being fed on a daily basis could quite easily lead to a skewed view of reality, which may lead to inappropriate decisions or actions. Reflecting on how we have come to our conclusions should be standard practice for leaders.
