I always believed that software development is an art and the design process is more of an inspiration than a mechanical process of finding nouns and verbs. Patterns, well I thought they were probably the worst creativity-repellents possible. So I was always lousy with UML until I realized that this aversion was compounded due to using MS Visio.
