If there is one characteristic that you acquire with a (regular) practice of Ashtanga Yoga is determination.
Which is defined as the quality of one who is firm in his purposes, intentions and actions, one who is persistent and sure.
By the discipline of a daily Ashtanga Yoga practice you will be led internally to understand the real meaning of this amazing feature. Because by systematically performing all those movements and postures you will find firmness, persistence and security in your body, mind and heart. And sooner or later, it will walk within yourself in every other area of your life, and in your relationship with others!
