Despite both not being a Christian, and when I was, not being a part of it that did Lent, a friend mentioned she was doing it last year and so I decided to do something too. I think the idea of giving up something for a month or more is a good experience. For Lent 2016 I gave up English media. And I kind of failed miserably, while still succeeding at the core goal of playing/reading way more in Japanese. It was probably one of the best things I did for my Japanese ability.
