The simple answer is no. However, knowing some simple fighting or self-defense applications for each move will help you remember some of tai chi’s choreography and how to string the moves together in longer and longer sequences. These applications also help you remember the specifics of how to move your chi while doing a form.
Sometimes it can take a setback to wake you up to what is valuable and what isn't. I had been fighting an intense legal battle with devastating effects on my business and on my health. I had to face starting over again very late in life. I couldn't do much about the drain on my time and money; however, I could do something about the drain on my health. Thank God for qigong!
