Dear Seth,

You’re only three years old, and at this point you are not able to understand this letter today. 1.

Life can be unkind. There will be people in your life who won’t be very nice. They’ll laugh at you because you’re different, or for no good reason. You will also face heartbreak and might be hurt by those you love.2.

Be open to life anyway. You’ll find cruelty and pain in your journey through life, but don’t let that stop you from new things. Don’t retreat from life, and don’t hide or wall yourself off. Be open to new things, new experiences, and new people. You will fall many times, but if you allow that to keep you from trying, you will miss many chances.3.

You will meet many people who will try to do better than you, in school, in college, and  at work. They’ll try to have nicer cars, bigger houses, nicer clothes and cooler gadgets.4.

Here’s a secret: life isn’t a competition. It’s a journey. If you always try your best to beat others, you’re wasting your life. Learn to enjoy your life instead.5.

Finally, know that I love you and always will. You are starting a really wonderful journey, and I will be there for you.

      Love,

Dad
