My biggest problems with practicing are, one lack of sufficient time (because one must be involved with working to make a living, among other extraneous nonsense, because one's wife and family unreasonably insist on eating regularly), and two, a wife who considers practicing an unproductive waste of time, since, A, I don't have a concert career, and, B, who do I think would be interested in hearing me play, anyway, and C, it's time taken away from the family. But I love her anyway.
