Taking a month or two to track spending habits will let you evaluate where your money is going and if it really needs to be going there. Also set up a separate bank account for savings, maybe even at a different bank, to remove some of the desire to spend the money. You have to value that more than you value what's getting you in debt. Making the resolution come to fruition may even take a change in environment. Perhaps more time outdoors or getting away from friends who lead you into undesirable actions.
Environment is very critical.
Asking them what they think and asking for help and support can be a boost. Companionship is very important to people. Having a clear, visual image of a resolution's goal can be a big help in reaching the goal, both Forgue and Quick said. A picture of that new home or a symbol reminding you to eat a daily apple can keep you on track. If you falter for a day, week or month or if the needed action seems too much to handle, don't count yourself out of the game.
