Those who see the glass as half full versus half empty anticipate the best outcome in a situation, but optimism is not just a stress-free way of living. Studies have shown that this type of positive thinking actually helps the brain, cardiovascular system, and immune system function better – which in turn leads to lower mortality and cancer rates. Plus, those who think more positively generally can overcome disability and illness better than those who think negatively.

But being optimistic is easier said than done. Though it’s a skill that can be learned, trained, and honed, some experts believe it’s a fundamental trait we’re born with. (Meaning, some of us are genetically predisposed to think happier, positive thoughts.) Regardless, there are plenty of things you can do in your daily life to be more positive – and in turn, happier, healthier, and more stable.

1. Find the good in every situation
Or the “silver lining,” if you will. Stop and ask yourself, even in the worst situations, what the positive side is – even if it’s a “could be worse” comparison.

2. Practice gratitude
Take a moment – or several – each day to express gratitude for the things and people you have in your life.

3. Stray from jealousy
Yearning for what others have that you don’t is a negative and unfulfilled way of thinking. Instead, treasure what you can measure – and yearn not for what you haven’t got.

4. Smile!
It’s a proven fact: just the act of smiling releases endorphins and tricks the brain into thinking a situation is more enjoyable than it might be. So smile, smile, smile!

5. Let yourself be upset
We’re not superhuman. Sometimes, you just need to cry, or get mad or frustrated when situations are difficult or things just don’t seem to go your way. That’s okay. Let yourself go through these emotions and forgive yourself for feeling them – they’re normal. As long as you don’t dwell, and you make an effort to shift your thinking before the anger or frustration turns into “doomsday” thinking, you’re still making progress. After all, 100% optimism isn’t healthy either!
