Having trouble looking on the bright side? If so, it could be your loss. Successful people aren’t all optimists, but one trait many of them share is the ability to see opportunity in unlikely places.
There’s the more immediate benefit, too, though; an optimistic mind-set simply helps our experiences feel more fulfilling and enjoyable. While many believe that optimism is something we’re born with in more or less finite quantities, we actually have some ability to shape our thoughts and actions–including our outlook on events. Here are some habits to help you to cultivate optimism.
Prepare your environment
The environment we try to build new habits in (or break old ones, even) has a huge effect on how successful we are. Environment in this case includes the people we spend time with and the messages we hear or tell ourselves, as well as our physical environment. The trick here is to ensure your environment is as conducive to you continuing your new habit as possible.
Start your day in an optimism creating way.
The way you start your day often sets the tone for the rest of it. A stress-free morning leads to less stress and better focus during your day. A work out early in your day leads to more energy throughout the day. And optimism while you are eating your cereal or traveling to work or school can help you to stay positive and constructive as you go through the ups and downs of your day. 
Smile More, Frown Less
“When we smile we are creating a happy, stimulating environment around us that draws others in. Frowning, on the other hand, shuts people out and has the opposite effect. Happiness, even in brief doses, releases Serotonin (the happy hormone). It makes the toughest days surmountable.”
