I’m 30 years old, and there are several things that life has taught me that I want to share with you．Here are the 4 lessons that life has taught me in the past 30 years．
1．Take Care of Your Body
Life is “unfairly” biased（偏向的） towards people who “look good,” like it or not．So it’s important that you do all that is in your power to look your best．   71    You will live longer, and you will live happier, if you take care of your body; you may even get promoted faster on your job．Remember that your health is really your greatest wealth．
2．   72     
No one taught me to save when I was growing up; no one told me the importance of saving．Fortunately I was able to learn the value of saving through reading great books like “The Millionaire Next Door”．What I want to teach others is to save at least twenty percent of your income．If you are to be wealthy, you must not just earn a lot, you must save a lot．
3．Think long-term．
In high school I was thinking about college, in college I was thinking about life after college．I’m designing my life and I’m making decisions today that will enable me to live the life I desire when I’m in my 40’s, 50’s and 60’s．You have to think long-term; you have to see the “big picture．”     73   
4．Realize the Power of Focus
Focus, focus, focus…     74    If you fail in this lifetime, you will fail because of broken focus．If you focus on the goals that are most important to you, you will achieve them．The problem is that there are so many distractions．  75   Winners decide to major on majors, and they even let important things slip, because they just focus on achieving what is critical to their goals．

Sharks have lived in the world's oceans for millions of years. A shark has an extremely good sense of smell. It can find small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. These powerful senses help them find their food.   1.
