40 days and nights of sacrifice

Many Catholics party and sin (well maybe just me) on Mardi Gras or Fat Tuesday because the next day is Ash Wednesday, which marks the start of Lent, where many Catholics give up something for 40 days and 40 nights.
Even though I’m not an active churchgoer, I follow the season of Lent not only to make my traditional grandmother happy, but to teach myself discipline. Whether it’s staying away from temptation or actually starting to keep those New Year’s resolutions, Lent gives me an extra push of motivation.

Not spending money on materialistic things would not only save me closet space, but it would also help save me money.
In past years, I’ve given up things like sweets and soda, which I now never drink. This year, I’m stumped. Lent comes during spring break, so giving up alcohol or fast food and sweets would just torture me. Some of my friends have decided on small goals like giving up swearing. Another friend said he would give up driving to work solo, and instead either carpool or take the bus.
So I may need your help on this. Below is a list of things that I may prospectively do during Lent:
— No eating after 7:30 p.m.
— No fast food
— Go to the gym every day for at least an hour
— Don’t spend money on materialistic things (clothes, shoes, etc.)
If you have any other suggestions, shoot them to me in the comment section. I’m going to pig out and max out my credit card before Lent starts! LOL.
Are you giving up anything for Lent? Even if you’re not, what could you live without for 40 days and 40 nights?
