“Difficult but possible is the key. That’s because more difficult goals cause you to, often unconsciously, increase your effort, focus, and commitment to the goal; persist longer; and make better use of the most effective strategies.”
― Heidi Grant Halvorson, Succeed: How We Can Reach Our Goals
This quote is a common theme and way of thinking that I completely buy into and how I live my life. This is also how I raise my children. I teach them about challenging themselves. I teach them that give full effort to things. To continually practice and work hard to improve. I also model this in my life as best as I can. Persist longer.
