We have all heard of people who give up cabbage (or something similar) for Lent because they do not like cabbage anyway! Such giving up is meaningless. Giving up something we really like, such as chocolate, might be more meaningful. But it depends on why we do it and what the result is. If all it does is increase our craving for chocolate so that we look forward to indulging ourselves even more at Easter, then it has been of little value.
