We know that Tshuvah works. The Nivim told us it does, Chazal repeat it many, many times, and we even have Yom Kippur, a day created specifically for tshuvah. The question isn't whether Tshuvah works, but why I don't make use of it?

Why is it that I don't stand there on Yom Kippur with tears flowing down my face, repenting, improving, ridding myself of a year's worth of iniquities? It isn't that I don't want to. It isn't even that I don't believe in it. It just seems that I don't feel a need to repent.

This Shmuz focuses on the motivation to do Tshuvah and the different parts of the Tshuvah process.
