Not quite: upgrade tools when they annoy you, not when they break. Almost the same, but you're not left suffering through using stuff that you hate. You'll never spend extra money on tools you don't use, because if you don't use it, you can't get annoyed! And if something somehow manages to break without annoying you -- perhaps you used it for a truly difficult task -- then you can and probably should go ahead and buy another of the same.
