How to Be Optimistic
Use positive affirmations. Write down short statements that remind you of what you're trying to change about the way you see the world. Put them in places where you'll see them every day, such as on your bathroom mirror, the inside of your locker, on your computer monitor, and even taped to your shower wall. Some affirmations to start with are:
"Anything is possible."
"My circumstances do not create me, I create my circumstances."
"The only thing I can control is my attitude towards life."
"I always have a choice."
"I choose to live my positive side of life."
Remember that life is short. When you feel pessimism clouding your judgment or you start to feel down about the future, remind yourself that every minute counts. Any time spent brooding guarantees nothing but less time to enjoy whatever life might have to offer. At its core, pessimism is impractical because it causes you to spend time dwelling on things that haven't happened yet and aren't guaranteed to happen. It also prevents you from getting things done. Pessimism breeds indecision. It's a waste of time, and time is a limited resource that you can't afford to take for granted.
Be a balanced optimist. Nobody is suggesting that you become an oblivious Pollyanna, pretending that nothing bad can or ever will happen. Doing so can lead to poor decisions and invites people to take advantage of you. Instead, be a rational optimist who takes the good with the bad, in hopes of the good ultimately outweighing the bad, and with the understanding that being pessimistic about everything accomplishes nothing. Prepare for the worst but hope for the best - the former makes you sensible, and the latter makes you an optimist. Being an optimist is not the same as being an extrovert. You don't have to be an extrovert to be an optimist. (www.vikihow.com)
