It's easy to sabotage your happiness and not even realize it. It may take time for you to override these destructive habits, but with concentrated effort you can do it.

In the inspiring new documentary, "STEP," we follow the stories of three young women who have to battle the subtle challenges that would have them believe they aren't good enough or are incapable of being successful. Their ability to overcome difficult home situations, societal pressures and expectations to reinvent their futures proves that anyone is capable of living their best life.

Here are five habits you can change that will reinvent your ability to enjoy happiness and success:

1. Mind reading

Sometimes we assume that we know what other people are thinking. We tell ourselves: "He must think I'm obnoxious" or "Wow, they must be really bored listening to me." These fabricated thoughts can wear down your confidence and happiness.

However, you have no idea what's going on in their minds. So, instead of sabotaging yourself assuming that they're thinking the worst, banish those thoughts and replace them with positives. Tell yourself that they think you're amazing and fantastic. If you believe they think you're amazing, you'll start acting amazing.

2. Looking forward to the future

If you wait to be happy until you win the competition or finish college, you are missing out on all the moments you could be happy today.

Don't postpone happiness. The cake is yummier when you're eating it, not when you're finished. The song is more beautiful when it's being played than when it's over.

Choose to be happy now instead of waiting for some elusive accomplishment to make you happy. If you don't learn how to be happy at any stage of life, you might not know how to be happy when you've finally reached that moment you're "supposed to be" happy.

3. Expecting people to be like you

It's easy to get frustrated with people because they don't act the way you think they should. "I would never do something like that," you say.

But it's unfair to judge people based on our own standards. Sure, you wouldn't do that, but they would. And that's OK. Relieve people of the need to live up to your high expectations and you will have a greater capacity to love them for who they are.

4. Hating failure

Of course, failure hurts. No one's saying it doesn't, but just because it hurts it doesn't mean it's not positive. Failure is the pathway to success.

When asked about his attempts to invent the incandescent light bulb, Thomas Edison said, "I have not failed, not once. I've discovered ten thousand ways that don't work."

In fact, the more you fail, the closer you are to succeeding. Your past is not your destiny.

5. Fortune-telling

It's easy to look at a situation and see all the worst-case scenarios. We assume we'll act like a fool on our date or that we'll mess up an important project. The worst part is we tell ourselves that we are preparing ourselves for these negative situations. In reality, we are entertaining negative thoughts that cause unnecessary anxiety.

Unless you have some kind of talent with tea leaves, you have no idea what will happen, so assume the best-case scenario in all situations.
