Someone who never loses their balance; or someone who is quick at regaining their balance when they have lost it?
Much of our education and unconcious 'life training' inclines us always towards the impossible fantasy of never losing one's balance. Yet have you met anyone who has achieved this without becoming a rigid fool who controls their environment in order to avoid appearing foolish?
In order to practise regaining your balance you must also practise losing it. Not all the time, but from time to time.
