I need to know how long is long enough. How long do I need to go without chewing my nails to consider my habit broken? It never used to bother me, but now I have discovered that nails are imporant in playing classical guitar, so I need to know how long. And the habit really needs to be broken, so that I can justify buying, or at least shopping for, a new guitar. You know where to reach me.
