Just read the Gang of Four Design Patterns book and I'm not sure if I feel enlightened or confused. Singleton, Factory, Observer, Strategy... the concepts make sense but applying them to real code feels forced sometimes.

Are design patterns genuinely useful in daily programming or are they academic exercises?

They're tools, not rules. Knowing the patterns helps you recognize solutions to common problems. But forcing a pattern where it doesn't fit is worse than no pattern at all.

The Observer pattern alone has saved me countless hours. Once you see where patterns naturally fit, they become indispensable. It just takes experience.

Start with the simpler ones — Singleton, Factory Method, Strategy. Those come up constantly in real code. Some of the more exotic patterns are rarely needed.
