Positive thinking for positive living

Stay positive and happy In our daily life, we always will found people who are always disagree in everything, they like to be dark, they always feel sadness, and they don’t feel the mood of being happy in this life. But I’ve found this quote that says something really interesting…  "Stay positive and happy. Work hard and don't give up hope. Be open to criticism and keep learning. Surround yourself with happy, warm and genuine people." Tena Desae Do you think that the author is right or wrong? Do we have in our hands our own decisions, or not!!
