Contagiously optimistic book about Alan's successes and his life as a gardener. Self effacing, quirky, and likable, Trowel and Error is the kind of book you read and feel content with life despite the now looming fact that as a child you didn't dream of growing up to be a insurance sales rep, engineer, secretary, or toaster sales-goon. The basic theme of the book is find the things you like, even if they are things no one pays you for, dedicate yourself to them and your likely to feel a certain amount of happiness in doing them. Plus you get to learn a bit about Alan's Titchmarsh's eclectic taste for crooked trees and mish-mash gardens. As far as celebrity autobiographies go (even though I wouldn't have known Alan from original Adam) its the best I've read.
