Mindset may be the single greatest factor for success in any individual. The mindset you approach a problem or task with will either set you up to solve and/or succeed or fail. Its something that ancient wisdom has stated in numerous different ways over thousands of years, but now science is confirming it more and more as time goes on. Mindset and mindfulness go hand and hand. Mindset is your thoughts and beliefs about yourself and the task, situation, or problem before you, whereas mindfulness is just being present and rooted in all the experiences of the present moment.
