Today is Ash Wednesday, which is the beginning of Lent. Lent is the forty day period before Easter, and people observe fasting and abstinence during Lent. The official requirements are to abstain from eating meat on Fridays, and only Ash Wednesday and Good Friday are days of fasting.
Of course, many people go above and beyond these requirements, and they give something up for the entire forty days of Lent. People will often give up something bad, like smoking or gossiping. People also give up good things, which are bad in excessive amounts, such as television or the Internet. And of course, people decide to take up good things for Lent, such as when someone works at a soup kitchen every week of Lent or someone pledges to say a daily rosary for all forty days. Almsgiving in particular is highly recommended as a good virtue to practice during Lent.
I'm going to give up playing videogames for Lent, because they have the tendency to eat up too much of my time. Even when I'm not playing videogames, they can sometimes distract me; I'll get so caught up with thinking about games that I don't pay attention to what I'm doing. And that should not be the case.
