"education is the latch key to success in life"

This statement is made by Gordon B. Hinckley. In my opinion I think this statement means is that always try your best in trying school because you will get something better in return. For example, you'll have a better life than you had before, or you'll have a good life for your future kids,etc...).Also I think it also means that to stay focus in school don't get distracted with problems or anything just worry about yourself. Don't be careless about school because if you do the grades you get are the ones that determine your destiny.
