My former colleague and all around great person, Annie English, has a book and a blog on how to retire young. The Toronto Star has reviewed it here: Here’s how this couple retired at 48 in expensive Toronto: Roseman | Toronto Star. Annie and her husband, Rich, were disciplined before retirement, and that discipline has paid off. If you want to learn how they did it, check out the Star article, or their blog, Retired At 48. If this is something you want to achieve, buy the book, too.
