One of the guys I respect is called Matt Cutts (Google dude). He regularly engages in 30 day challenges to develop his character.
Another guy I really respect is Jesus (son of God). Linked with Jesus is Lent (the three pillars of Lent are prayer, fasting/giving stuff up and almsgiving; starting this Tuesday)
So when you put the 2 together = a good reason to give stuff up.
I have decided to give up both alcohol (actually quite easy for me) and chocolate (worse than a veteran drug addict giving up his stash of cocaine and heroin) for Lent.
Wish me luck.
03/03 update: I’ve failed on the alcohol front however surprisingly am still going strong on the chocolate challenge.
