Productivity Books That Use Curse Words

A lot of productivity books are using curse words in the titled. And i just want to say that i don't like that, honestly. I feel like there's been a little bit of a a boon lately with this whole topic of will power. So you can look at your situation after the fact, and you can say, i guess i ran out a will power, and that's why i didn't go to the jim. But how does that really help you going forward?
