Working out 24/7 doesn't make you a more healthy person quicker. Not eating won't make you that healthy skinny that has become trendy. Taking a 20 credit hour semester doesn't guarantee you walk out of college with a 4.0 and a job lined up. In fact, going overboard for quick results rarely gets us the ending we're looking for.
Doing things in excess or to the extreme often has a more negative than positive impact. Working out too much typically leads to injury. Starving yourself causes major health problems. Taking those extra classes could mean burning out or over stress and ultimately lowering your GPA and ability to focus.
Expecting extreme measures to give medium results usually misses the mark. There's a reason for the "happy medium" mentality. If you really think about it, most of the things we desire lie in the center of a balance. Moderate exercise and healthy portions grant a happy, healthy body. Balancing credit hours, enough sleep, and rest time create a more profitable learning experience. The best places in life are usually results of moderation.
I plan on starting to live with more moderation. It is a practice, but the results are what I'm after. Practicing moderation also helps avoid the damage that extremes like to create. So join me in living a life finding the balance. Find areas in life that you've been expecting extreme measures to give you happiness.
