No, not until you understand why you have such a behavior. I honestly don't think it's something you can accomplish alone as there lies a reason, maybe a deep seated reason, why you choose destructive behaviors over constructive, enhances behaviors. Talk to you dr., that's where to start. He/she can recommend someone for you. Good luck to you, my friend.
You would need therapy to figure out what exactly makes your personailty 'self-destructive' you just basically have to sit down and ask yourself a lot of questions lol

First of all, what do you consider a self-destructive personality. most people destroy opportunities for themselves because their mental life says that they don't deserve it, so they talk themselves out of it or cause things to happen that will destroy it. The first thing you need to do is watch how you talk to yourself. It is SO important that you start giving yourself credit for the things that you do well. Many people go through life only focusing on the things that they do wrong, and breeze over the things that they do right. We are creatures of habit. If you think bad about yourself over and over and over again, then that is how your thinking is, and you will create an outside world that matches the "person you see." Just as there is a downward spiral, there is also an upward spiral. You have to start saying positive things to yourself, build your esteem yourself. Stay away from people who doubt you, say bad things about you, and just continue to say how great you are. As soon as you feel better about yourself, the rest of your life WILL reflect it. Start now. Look in the mirror and say that you are an awesome person and list ten things that you have done well. Write them out, and repeat them to yourself everyday. Next week come up with ten more. Repeat them to yourself (in your head) everyday, but just keep adding more and repeat them all. Eventually, you will train your brain to think you're great
not if that person continues to be self destructive.
