A tenacious grip on our own ideals, irrespective of hurdles, would propel us towards self-actualization!
Success is determined not by whether or not you face obstacles, but by your reaction to them. And if you look at these obstacles as a containing fence, they become your excuse for failure. If you look at them as a hurdle, each one strengthens you for the next.
Success works as a cycle - growth and contraction, balancing and unbalancing - all while you're encountering hurdles that get higher and higher over time.
