We each have within us some inner enemies that can quickly kill off our confidence. They drain our lives of potential and our purpose, and they fill us with deep regret. Left unchecked, they can unfortunately quickly erode our grandest plans and our noblest intentions.

See if you recognize any of these 12 confidence killers in your own life. If you do, you need to crush them now. Your future depends on it.

1. Feeling unworthy. Self-confidence comes when you feel worthy of who you are and what you’re accomplishing–when you believe in yourself. When you think or say you’re in any way not good enough, you’re rejecting your own value. Combat these feelings by thinking of the things you appreciate about yourself.

2. Constantly overthinking. One of the worst enemies of confidence, overthinkingleads to negativity. It twists things around, makes you worry, and makes everything appear so much worse than it actually is. When you give up overthinking you’ll be amazed to see how many problems it caused.

3. Surrounded by negative people. Some people think being alone makes you lonely, but for me being surrounded by the wrong people–and negative people in particular–is far lonelier. Negative thinkers will never do you any good, so stay far from them.

4. Dramatizing everything. If you’re scripting negativity and trouble in your mind, drama is bound to result. But it doesn’t have to be that way. Whether you believe it or not, you have the power at any given moment to let go of the narrative so far and remind yourself that this is not how the story ends.

5. Telling yourself you’re not smart enough. Nothing hurts more than trying your best and still not feeling smart enough. To regain your confidence, you have to literally tell yourself, “I am smart enough to succeed. I already know a lot, and what I don’t know I will learn.” Each of us is smart in what we know–we just have to acknowledge it.

6. Thinking that good things only happen to other people. Why do we always think the grass is greener on the other side? The truth is, if you were to get the baggage of others you would likely be glad to give it back. You never know what other people are carrying, being grateful for the good things you do have and be patient for the rest. Maybe it’s your turn to be the good thing that happens to someone else right now.

7. Living in the past. What’s done is done, as the old saying goes. We all have decisions we might undo if we had a choice, good times we took for granted, events we wish we could have avoided. You can’t change the past, but find strength and hope in the fact that you can always change today.

8. Counting your failures. We all fail sometimes–some more than others. It doesn’t make you unworthy or less intelligent. Remember, the only people who never fail are the ones who play it far too safe.
