Everyone around us are negative to some degree. Why is this? Why can we not be i a more positive state of mind and focus on improvement and self worth rather than putting others down and attempting to crush their dreams.
If you want to be a world champion work hard, focus and become a world champion. If you want a Blackbelt do the same. Some problem may just want to be a great kicker. So what. Let them be who they want to be.
The positive mindset will keep you focussed on your goal or goals and enable you to better your way of life.
Surround your self with positive people and you will have a positive life.
