Say your Goal is Quit Smoking

You may have individual steps to help you do that.
A step is referred to as a bite.

A bite could be something like:
[ ] Throw away all my ashtrays
[ ] Convince my spouse to quit with me
[ ] Clean out my house of anything pertaining to cigarettes
[ ] Make a donation to the Lung Cancer society

Each step you take moves you futher towards your goal.
