“If you don’t believe it will happen, it is almost guaranteed that it won’t. You simply cannot achieve a goal that you do not believe you can achieve.”

- From The Answer by John Assaraf and Murray Smith

“Being optimistic involves a choice about how you see the world.”

- From The How of Happiness by Sonja Lyubomirsky

- From The Master Key System by Charles Haanel

“Happiness is not merely contingent on what we do or where we are but on what we choose to perceive.”

- From Happier by Tal Ben-Shahar

“The man who thinks he can and the man who thinks he can't are both right.”

“Go on a Negativity Fast. For the next thirty days, do not watch, listen to, or read the news.  Avoid negative and sensationalized media. Ignore all gossip about misbehaving reality stars and their ilk; there is nothing positive there. Avoid all negative people whenever possible.  Refuse to say anything negative or engage in conversation with a negative slant. Think only positive thoughts. Optimistic thoughts lead to optimistic action, while pessimistic thoughts lead to self-defeating action or none at all. You can choose your own thoughts and replace those that don’t serve your purpose.”

“Gratitude is the attitude that changes everything. An attitude of gratitude adjusts your mind to focus on the positive. Thus you’ll see, discover and create more of the same, experiencing more abundance, prosperity, well-being, love, joy, and happiness.”

- From Living Your Best Year Ever by Darren Hardy

“Scientists are finding that even on the days when you don’t feel like you have anything to be thankful for, just asking the question ‘What am I grateful for?’ is enough to change the chemistry of your brain. This simple practice trains you to look for everything that is going right in your life so you can start to more effectively water the flowers and not the weeds.” “The more you stimulate the neural pathways through practicing gratitude, the stronger and more automatic they become.”

- From Stress Less, Accomplish More by Emily Fletcher

“There’s a vast difference between optimism and wishful thinking. One is a mind-set that expects progress through effort, and the other is nothing but a bulwark against the fear of failure. Someone who is optimistic expects the best while actively working to bring it about. Wishing externalizes responsibility and hopes that everything lines up according to plan, but doesn’t do anything to actively bring about the desired change. Someone who operates from a place of wishful thinking is—in essence—a closet pessimist.”

- From Die Empty by Todd Henry

“You don’t just owe it to yourself to be an optimist; you owe it to everyone around you. A pessimist sucks the energy out of the room. Nobody wants to put up with somebody who’s bitter and cynical all of the time. Not your friends, not your teammates, not your boss, and certainly not your spouse.”

- From Relentless Optimism by Darrin Donnelly

“Positive thinking leads to positive outcomes. Study after study proves this. Researchers have found that optimistic people live longer, live healthier, have more energy, have more successful careers, make better decisions, are more productive, are less stressed, have healthier relationships, and (not surprisingly) are much happier than pessimists.”

- From Relentless Optimism by Darrin Donnelly

“You want to know what your life will look like a year from now? Listen to what you’re saying when you talk to yourself. Your self-talk determines your future.”

- From Relentless Optimism by Darrin Donnelly

“Optimism enables you to confront and overcome all obstacles and challenges. It gives you the power to persist. To meet any challenge, you must first believe that you can. Every challenge successfully met begins with a vision, and that vision is driven by optimism. You get what you expect.”

- From The Only Sales Guide You’ll Ever Need by Anthony Iannarino

“Whether you think you can, or you think you can’t, you’re right either way.”

- Henry Ford

“Nothing can stop the man with the right mental attitude from achieving his goal; nothing on earth can help the man with the wrong mental attitude.”
