There are always two stages to learning a new exercise. Firstly getting the structure correct, solving technical problems and getting it to flow. Secondly fleshing out the exercise with energy by falling in love with it and investing it with real heart and soul. These two approaches tend to work against each other, so once you've learnt an exercise you need to tell yourself: 'Now I can do the thing it's time to discover its internal secrets by really practising it.' Most students never reach this second stage because they insist on moving on before they're ready. Forever starting at the beginning. Never growing up.
