Just Because You Can Doesn't Mean You Should
Beginners usually go all out for every pose, attempting the most difficult degree of every pose. More advanced practitioners are not more advanced because they can do more challenging poses—they're more advanced because they have the wisdom and intelligence to know when to back off. In your life, you CAN juggle 1,000 things at once, a high-stress job, family, volunteer work, friend, etc… but that doesn't mean you should. Take on only what you can do intelligently and with grace.
