Okay, there are three types of habits:

+ only

- only

+/- (both)

The first two will always decay back towards yellow on cron automatically. The third type has a set value that doesn't decay -- that is why it is doing more damage to you on successive clicks. You do indeed counterbalance it by clicking plus on the same habit (it'll go back towards yellow.)

Therefore, you want to use a +/- when it doesn't matter how long you have/haven't done something -- a 'whenever' habit, good and bad. You use a +  or a - habit when not doing it consistently means something. They're harder to push towards red or blue without daily efforts, but it's doable.
