There are times that happiness can seem so fleeting, we don't even notice when it's here. The trick to achieving a level of joy you're able to maintain, however, is doing small things every single day to work towards happiness--rather than trying to achieve it all at once.

Here are five things really happy people do every day, especially when the going gets tough.

1. Exercise

It seems cliché, but physical wellness equates to mental wellness. Make sure you're taking care of your body and offering it some kind of physical activity every single day--even if it's only for 10 or 15 minutes. Consistency is key to feeling good--about yourself and everyone and everything else in your life.

2. Be kind

Even though there is the old saying that "nice guys finish last," it's important to recognize the positive impact simply being kind to the people in your life can be. Doing small gestures--like holding open doors, or doing a favor for a coworker--can go much, much farther than you would think. Choose to be kind every day; your happiness will definitely improve.

3. Surround yourself with people you love

Why spend time with those that make you feel bad about yourself, or with toxic people who want nothing more than to suck the life out of you? Choose your company carefully and surround yourself with those that you love. You'll definitely experience a lot less negative energy than you would otherwise--and you'll also get to build real relationships with those you genuinely care about.

4. Be grateful

Just like kindness, being grateful goes a much longer way than we ever think it does. Simply thanking people for their work--and showing those you love that you appreciate them--actually resonates with people much more than you think. The reverse of this is also definitely true; the more people express that they are grateful for the work you do, the better you'll do it.

5. Let yourself be happy

Sometimes, we are the biggest obstacles holding ourselves back. Be happy. Let yourself enjoy things. Find comfort in laughter, love, and being in the company of those you love. Your mind, body, and soul will thank you.
