Today is Ash Wednesday, the first day of Lent. Frankly, I've given up a lot of material things in ten years as a full-time freelancer. For the past several Lents, I've reevaluated emotions and traits I once held onto dearly, parts I felt made me who I was. I didn't have a solid reason to keep them, only that I already had for so long.
I don't go in fixated on one particular thing I'm giving up, but replace my own desires with the needs of others.
