Dear Seth, 

You are only three years old, and at this point in your life you are not able to understand this letter. But some day when you 1 , I hope you will find something 2 in what I am going to share with you. 

Life can be 3 . There will be people in your life who won't be very nice. They'll 4 you because you are different, or for no good reason. You will also face heartbreak and might be 5 by those you love. I hope you don't have to face these too much, but such things happen.

Be open to life anyway. You'll find cruelty(残忍) and 6 in your journey through life, but don't let that 7 you from finding new things. Don't retreat（退却）from life, and don't hide or wall yourself off(把自己隔离). Be open to new things, new experiences, and new people. You will 8 many times, but if you allow that to stop you from trying, you will 9 many chances. Do remember failure is a stepping stone to10 .

You will meet many people who will try to do 11 than you, in school, in college, and at work. They'll try to have nicer cars, bigger houses, nicer clothes, and so on. To them, life is a competition. However, I believe life is a 12 . If you always try your best to 13 others, you are wasting your life. Learn to enjoy your life instead and you will make it a journey of 14 , of learning and of love.

Finally, know that I love you and always will. You are 15 a really wonderful journey, and I will always be there for you. 

Love, 

Dad
