As long as what you are doing works for you then that is fine, we are all different on our path or at different stages in dance. If you like what you are doing then stick with it. For myself and many of the others who are now working these ideas the biggest comment I hear is why didn't we learn this earlier!!!! I wish I had started out with these principles rather than 15 years into competing. Luca & Loraine Baricchi push that the principles of dancing/body mechanics are imperative for everyone, especially competitiors, if they wish to be successful.
Here is a mini workshop with Edite Danuite speaking about the some of the principles of dancing. It may be useful for some people so I will post it here.https://www.youtube.com/watch?v=dhPH5DoDUVo
There is a better one with Luca and Loraine but it just gets into it then stops after 4 min. so unless I can find the whole one no use posting it.
