1. Start as soon as you wake up each day. Scientists have found that your subconscious may be most active right when you wake up. So training yourself to think more positively in the morning can set you up for a better day overall.
Something as simple as looking at yourself in the mirror and saying, "It's going to be a great day" can have a big effect.
2. Drown out the negative thoughts. People have a tendency to put more weight on negative experiences. One study found that we need at least FIVE times as many positive experiences to counteract one negative one.
3. Focus on finding more positivity. Fill your day with as many positive thoughts as possible, whether that's bookmarking sites with funny videos, seeking out encouraging stories, or reading uplifting quotes.
4. Hang with people who make you happy. Positivity and negativity can be contagious. If you spend your days hanging around with someone who always sees the worst in a situation, you're more likely to get caught up in it too.
So think about the people you spend the most time with . . . and which ones lift you up and make you laugh. That doesn't mean you need to cut out anyone who's negative, but just keep it in mind so you don't get sucked in.
