Bad habits are usually rephrased as "Replace X" or there is a positive form of that habit or a goal.
Quit Sugar" => "Replace Sugar" => "Eat more Vegetables" => "Lose Weight" => "Body Fat to < 12%"
Why? Because bad habits are hard to get rid of. One also needs to find something else to do (=replace) the negative habit. Therefore instead of reminding yourself about the bad habit one should try to define a positively formed goal. Or add another goal to support the new behavior.
