In today's world we need everything fast and quick. If we need something we google it. But dancers know that there is no substitute for hard work and perseverance. Acquiring a news skill takes time. Commitment over time is the very antithesis of modern living and is the core of dance training.
In dancing "Failures" become opportunities. In dance class you are only entitled to what you earn. And what you earn doesn't even necessarily have to be perfect dance technique. The most hardworking students are the ones that in the end reap the most benefits. Every student worked hard because they didn't have the feeling of entitlement.
Cutting corners is not possible in ballroom dancing. If you follow all the steps, improvement will flow. But if you try to avoid and skip certain levels, it will be hard to become advanced. Anyone with aptitudes will tell you that at some point they went back to fill in the gaps.
In a world that is so concerned about appearances, the dance teacher will tell you that what other people think is not the most important thing. If you can't do it today, there is always next class and you are already on the way because you have begun.
