     One day, a young man was cleaning out his late grandfather's belongings when he came across a bright

red envelope. Written on the front were the words, "To my grandson." Recognizing his grandfather's

handwriting, the young man opened the envelope. A letter inside read:

Dear Ronny,

     Years ago you came to me for help. You said, "Grandpa, how is it that you've accomplished so much in

your life? You're still full of energy, and I'm already tired of struggling. How can I get the same enthusiasm

that you've got?"

     I didn't know what to say to you then. But knowing my days are numbered, I figure that I owe you an

answer. So here is what I believe.

     I think a lot of it has to do with how a person looks at things. I call it "keeping your eyes wide open".

     First, realize that life is filled with surprises, but many are good ones. If you don't keep watching for

them, you'll miss half the excitement. Expect to be thrilled once in a while, and you will be.

     When you meet up with challenges, welcome them. They'll leave you wiser, stronger, and more capable

than you were the day before. When you make a mistake, be grateful for the things it taught you. Resolve to

use that lesson to help you reach your goals.

     And always follow the rules. Even the little ones. When you follow the rules, life works. If you think you

ever really get by with breaking the rules, you're only fooling yourself.

     It's also important to decide exactly what you want. Then keep your mind focused on it, and be prepared

to receive it.

     But be ready to end up in some new places too. As you grow with the years, you'll be given bigger shoes

to fill. So be ready for endings as well as challenging beginnings.

     Sometimes we have to be brave enough to move from the familiar to the unfamiliar. Life isn't just reaching

peaks. Part of it is moving from one peak to the next. If you rest too long in between, you might be tempted

to quit. Leave the past in the past. Climb the next mountain and enjoy the view.

     Dump things that weigh you down emotionally and spiritually. When an old resentment, belief, or an

attitude becomes heavy, lighten your load. Shed those hurtful attitudes that slow you down and drain your

energy.

     Remember that your choices will create your successes and your failures. So consider all the pathways

ahead, and decide which one to follow. Then believe in yourself, get up, and get going. 

     And be sure to take breaks once in a while. They'll give you a renewed commitment to your dreams and

a cheerful, healthy perception of the things that matter the most to you.

     Most important of all, never give up yourself. The person that ends up a winner is the one who resolves

to win. Give life everything you've got, and life will give its best back to you.

                                                                                                                                       Grandpa
