Success is an equation requiring the following variables, variables that you control or control you. Success equals energy plus direction plus purpose. If you do not have direction, or you lack energy, or worse still, your purpose is lacking, then you will be like an octopus on roller blades...going no where with lots of motion.
Be purposeful, have a direction, bring energy and you will succeed in life. Without these elements, your efforts will result in destruction rather than success.
