Theory vs. Practice

Have you ever noticed that most people generally have all the right answers when you bring a problem to them? They explain in detail exactly how you can fix it and what you should do. I generally think I have all the answers too when we are talking about certain situations or management ideas or how to execute a job well. But then comes the time when I actually am in a situation, or need to execute a job, and suddenly I realize that all the theories I had were nice, but were just words thrown around at coffee time. Actually doing things takes work, and dicipline. I find at times we forget to see all the details when we are making theories, but act like we know it all. Sometimes I think it would be better to just get to work, pay attention, and get it done. Okay so I'm theorizing :-)
Also we might want to stop listening to the people who have so much to say, and pay attention to the the ones who have practice. They usually are quieter cause they know they don't have all the answers. And sometimes they are hard to find cause they are busy doing the things we only theorize about.
