Hello everyone,
In order for anyone to change a behavior, it's necessary to realize that, to come to that knowledge, and yes,... desire it as MS said.
Repentance is the first step, along with faith in the Lord Jesus Christ,... then, depending on what the person's battle is, getting help from every possible source is a good idea as abqfriend pointed out as well.
However, we must remember the Savior's Atonment... which is the most powerful & merciful gift we can call upon to help us with our personal battles.
The Savior went below ALL things for us (Things that I won't and/or have not yet experienced in my life), in order to KNOW HOW to came to our rescue!
Going below all things means He took upon Himself ALL infirmities that affect mankind, and ALL sins mankind commits, without sinning Himself.
Taking upon Himself means He experienced the pains, difficulties, struggles, etc. of diseases, grief, pains, etc. cased by one's bad choices or caused by other's bad choices, spiritual infirmities & diseases as well whatever they may be. Taking upon Himself, He felt those things on Him, but doesn't mean He suffered of or did any of those things Himself while He was alive.

We can drawn upon the power, enabling & strengthening power of the Atonement to change something we are dealing with, that positive thinking, and many other good methods to help us be free from are not helping. He KNOWS HOW to succor (Come to our escue) us because He know what we feel, and has the power to enable & strengthen us to either deal with it like Paul, or to deliver us completely!
To enable: to give a person power, to make him/her able to do something, to empower

Elder Bednar's talk was one of the most detailed talk that helps us understand & make use of this wonderful and marvelous gift the Lord gave us!

And it is my testimony that we all can be delivered of any behavior/attitude/circumstance/... that is harmful/bad/foul... through HIS enabling power or strengthened to bear His will on us.
It's a glorious gift from our Savior, and He's intention was to help us... Let's unwrap it and make use of it!

Warm regards to all of you!
