I'm about 15 years older, so I grew up under the Old Rite and the old practices. Frequent confession was one of them.
I can still remember how shocked I was when we were told we were going to confession "too often." The clergy and Vat II created this situation, and the clergy are the ones who are going to have to tell people it's important - and then show up in the confessional more than 1/2 hour per week.
Fer Pete's sake, they can sit there for an hour and read a decent book, their breviary (do priests even do this anymore?), or pray for an hour if nobody shows up. It's not going to kill them.
