Negativity drains your whole day energy

I have spoken to my wife regarding how negative thinking drains all the energy of a person. Everyday in our life, from beginning every morning are negative in nature. Things tends to get messy, before we even reach the office for our everyday works we already drain our energy by 80%.. from brushing her teeth which saw her gum was bleeding, listening to radio about accident here and there, traffic jam, etc, etc... how our mood change when we arrive at our work place. You feel terrible to start the day... you only left 20% of your energy to do work.... how good would that be if you can double it to 40% and practice to stay positive.. all those are small matters and we should not let those affect our day, and should not let it to drain your energy... talk to yourself, tell yourself today will be a perfect day, the best day of your life, and I will not let small matter ruin my day. Always remember, if someone makes an arguments with you, and you feel bad.. that is energy sapping. Refrain from doing so, be positive.. think of the good things... think of you are doing the work for your children , or for your future (you are happy to do it for yourself or your kids).. and not for your boss...or the person that offended you
