Have you ever thought about the people who are leading a difficult life, if not then please be a human. Just think once, see around yourself. May be there is scarcity of money, someone with poor health , improper relations, tensions may be of family, office, kids and many more which we all can never imagine also. So allay yourself and be thankful for what you have. Every moment with delusions would inculcate negativity in and around you.
Look at you , hear and focus on good things, and always remember….
Positive thinking enables to see the invisible, feel intangible, feel worst as worth because source of happiness is within you and by you.
