That's why I mentioned it gently at the end -- just as a friendly reminder. I didn't want to accuse anyone.
Same. No individual was accused and there was no need to get defensive (and protest too much, as it were). People's motivations are between them and God. I just find this kind of thread (which we've seen before) to be rather useless. As you point out, everyone is different and so each individual needs to decide (together with his confessor) what might be appropriate for himself, and so sharing thoughts is relatively pointless. We all know the endless possibilities out there in terms of prayer, fasting, and almsgiving (including donation of one's time). I also agree with your caution regarding tackling one little thing at a time, until it becomes a habit. There's a great danger in going from 0 to 100. Even in things unrelated directly to the spiritual life, people invariably fail when they make radical moves. That's why nearly all "diets" fail and all New Year's resolutions fail (where you're going to go from couch potato to training for a marathon or weight-lifting competition from one day to the next). Make one little change at a time until it becomes a HABIT and you do it without even thinking about it. Then add another little thing. And what you add could depend on your predominant vice. So, for instance, a couple of my kids hate eating, and so "fasting" does not require any virtue for them.
With fasting and other penances in particular, pride is always a HUGE danger and can be worse than any attachment to food. I love the story of St. Francis of Assisi where he had gone without eating meat for several years. At one point, he was a guest at someone's home, and this person served meat. St. Francis ate it without giving it a second thought. One of his brothers marveled, thinking that it must have been a great blow to him to have ruined his "streak". St. Francis replied that there was no hesitation, since charity toward his host required that he eat what was served. There was zero motivation in him regarding pride, "Ah, I haven't eaten meat in 10 years, see." That meant nothing to him compared to charity.
