Self development starts with identifying and becoming aware of our habits and emotions that cause self destruction and dissatisfaction. We all are bundles of patterns that we have cleverly developed (subconsciously) over time to make us successful in particular endeavours. These patterns are warriors in the right circumstances but left unchecked, altered or updated to our new circumstances, work against us.
Therefore, though we are working hard and trying to do everything that once worked for us, we fail to extract similar results today.
