Just about anyone who believes that they are, at any level, a sex addict has made some attempt to change. It might have been just for a day, but they tried… and failed. If sometime in the past have attempted to stop sex addiction and failed in doing so, the hardest barrier to overcome to succeed is the thought that you can't succeed.
Think of it this way: there is no such thing as failing; only quitting. Let's go back to the time you were learning how to drive a car. At first, you don't know how the pedals work and even how the car steering will behave once you step on the gas. You were scared and you might have come to a point that you believed you can't. But still you persisted. You learned how to drive because you didn't stop until you can actually drive a car. You may say that it is not a complicated case as compared to compulsive behavior but that's also the approach you apply when you want to succeed on other things, including overcoming sex addiction.
If you have a fear in failure, you can overcome it by persistence and finding a successful approach.
Instead of asking, “What if you don't believe you cannot overcome sex addiction?” ask yourself this question: "What if my condition isn't hopeless? What if I can really overcome sex addiction?"
There is no secret in overcoming sex addition. You just need to believe you can through a successful approach.
Good counseling will give you the right knowledge on how you approach the process of healing. It will also help you get motivated and keep your feet on track. The effort, however, is up to you. Just like learning how to drive a car, you need an instructor to teach you and guide you through the process of overcoming sexual obsession.
Yes, past failures can affect the way you look at things, but it certainly will not help—the reason why you are following a successful approach.
The very obstacle in overcoming your condition is in you. All your bad experiences that are wrapped in one big part of your brain that continuously trip you as you make every progress, giving you the idea to quit. The thing is, once you have overcome this obstacle, consider yourself successful. Remember, if you are willing to make an effort, the right process together with a good counselor will help you succeed.
