I subscribe to Seth Godin's daily blog post which I really enjoy. Yesterday's post was, The self-defeating quest for simple and easy. In creating college lists, standardized test prep, the college essay, the college application process, high school classes and college classes, this applies. Take the time to do it right. There are no short cuts and it is a waste of your precious time to look for them. As it relates to test prep, take practice exams, take the time to analyze what you missed and work on weak areas. Take the time to READ and review.
In high school, take the time to learn the material. Short cuts may work short-term, but, in the long run, they usually hurt.
In college, seize the opportunity to absorb as much as you can. You are given the gift of TIME in college. Use it wisely. You never know what it will benefit you to know in the future when you do NOT have the time to re-learn it.
Time spent productively pays off. Enjoy the process.
