Juliette at Honeysuckle Faire has done an excellent series of pages that I recommend you read - they're about important things that all of us deal who have horses deal. Juliette works on retraining TBs, but the things she writes are applicable to all of us, I think. Although each of us may have a somewhat different goals with our horses, or go about things in a slightly different way, there's a lot in there to learn from. The first page is about a philosophy of retraining, and really about how to build a relationship with your horse. The second page is about finding confidence with horses - and I'll bet there isn't a rider out there who hasn't struggled with issues of this kind - particularly us adult reriders or new riders, or those who've had problems or wrecks with their horses. She also has a third page on her philosophy of horsekeeping - with one really excellent link on winter horse care, and a fourth page on helpful books - there are a couple listed that I'm going to run right out and buy.
Sit down with a cup of coffee, enjoy your reading, and be sure to leave her a comment if you like what she's written. I've also created a new sidebar with links to these posts (for my own convenience as well as yours) so they'll be available for rereading, and she also has sidebars on her blog.
