'Without continual growth and progress, such words as improvement, achievement, and success have no meaning'. -Benjamin Franklin.
Life has many scenarios that we can learn from, sometimes the effort we put into making an achievement is like cutting down a tree, the bigger the achievement the more effort and energy we need put into it. A big tree will not just fall with a single cut, but with continuous effort we will get to our destination. Success can be compared to a man embarking on a journey, with success being the end destination. The closer we get, the more energy we need to put to cross the finish line. What we need is the principle of focus in whatever scenario that is applicable. If at all we fall short, we simply need to look back and pick the lessons, we can't do anything without applying the necessary lessons. The same principle of success is applicable in all endeavors, what you put is what you get.
