Does it seem to take forever to get better at dancing?

You may actually be getting worse, if you are reinforcing bad habits.

There is only one way to get better.

You have to practice the right things.

To practice the right things you need to (1) know what they are and (2) get feedback to make sure you are doing them correctly.

See this article for How to Evaluate Your Dance Instruction So You Know What to Do.

The two best places to get feedback are from a video camera and from your teacher.

Whenever you practice, use a video camera. Watch yourself on video. Watch videos of other people that you want to copy. Compare yourself to them.

It is easy to find fault with yourself. Find one thing that you are doing that you want to correct. See what the person that you like does. For example, if you do not know what to do with your hands, see what the person you want to copy does with his or her hands.

Your teacher can give you feedback and solutions that you might miss for yourself.

Welcome feedback from your dance partners. They can help you identify problem spots you need to address.

However, instructions from your dance partners may not be the best solutions. For example, when a partner tells you you need to have pressure in your frame, you do not need to create pressure in your frame. Probably, the problem is you are moving your hands without moving your feet. What you need to do is to move your hands by moving your feet.
