The truth is, it's hard to define what exactly a "good person" is, let alone to create a step-by-step method to become one. One thing that isn't so hard, however, is doing the little things, which really do go a long way. Everyone wants to make the world a better place, but no one really knows how to do so. Instead, we all sit back and wait for someone else to take the wheel. Here's a thought: if we all try to become better people now, perhaps we can rid the world of the hate and cruelty that exists -- sooner rather than later. It starts with small steps, so here are some simple things you can do to make an impact on not only your life but on the lives of the people around you as well.

1. Hold the door.

It may seem like common knowledge, but you'd be surprised how many people don't hold the door open for the person right behind them. Sometimes we are distracted and just not paying attention, but we should all try to make it a point to be aware of our surrounding situations. And we shouldn't need any other reason beyond the fact that it's just polite. Show the world that chivalry is not dead.

2. Say "thank you."

Whether it's to the stranger holding the door or to the waiter refilling your water glass, or maybe a long-winded thank you to a loved one for all that they do for you -- always be thankful. It's such an easy thing to do, and it can make anyone feel appreciated. Be grateful.

3. Put your phone down.

I know, I know, you've heard it again and again. But seriously, being on your phone when you are spending time with people is rude. Instead of incessantly refreshing your Instagram feed or trying to decide which Snapchat filter to use, actually focus on the person who took the time to be with you. They're worth way more than how many likes you get.

4. Pick up trash.

Even if it's not yours, pick up trash that you see lying on the street. Making the world a better place includes making the environment a better place. Instead of adding to the problem, do your part to fix it. It won't hurt, I promise.

5. Smile.

Whether you know the person or not, pass along a friendly smile. It could be exactly what they need to turn their bad mood around. Not only that, but psychological studies have proven that your facial expression can actually influence your mood. So, not only will you be brightening another person's day, but you'll feel happier as well.

6. Call your friends just to see how they're doing.

It'll make them happy to know that you were thinking about them, and it'll keep you guys close, especially if you don't see each other that often. Whether they've had a terrible day or a great one, they'll really appreciate having someone to share it with.

7. Stop judging.

This is easier said than done. Unfortunately, we all judge each other, whether we realize it or not. Judgement of others only creates jealousy and negative emotions, so we should all make a conscious effort to stop.

8. Work out and eat healthy.

I'm not saying that you have to go to the gym every day or start yourself on some ridiculous diet, but exercising and eating better really will make you feel better and lift your mood. And if you're in a better mood, you'll be more likely to want to share that with the rest of the world.

9. Tell your family you love them.

Even when life gets hectic, don't forget to tell them that you love them, and always make time for them. They are more important than you know, and having a close relationship with them can have a huge impact on your life.

10. Admit your mistakes.

We all make them. No one is always right, and realizing that and recognizing your faults will help you to humble yourself and to become a more understanding person. Don't be too stubborn.

11. Stop complaining.

As my mom always says, "life isn't fair." Every single person goes through personal struggles. Do not dismiss their problems simply because you feel as though yours are more significant. Different things affect different people in different ways. Be supportive, and realize that you have it way better than you think you do.

12. Pray.

Even if your not religious. On good days and bad ones, pray. Be gracious. Seek advice. It will relieve stress. And who knows, you may even get a miracle out of it.

13. Give what you can.

Whether it's donations, time or attention, give everything of yourself that you possibly can. Put you're whole heart into everything you do, and I guarantee you, you'll get something out of it.
