Dear Seth，
You're only three years old, and at this point in your life you can't read, much less understand what I'm going to try to tell you in this letter.But I’ve been thinking a lot about the life that you have ahead of you, about my life so far as I reflect on what I’ve learned, and about my role as a dad in trying to prepare you for the trials that you will face in the coming years.
I hope to help you along your path by sharing some of the best of what I've learned. As with any advice, take it with a grain of salt.What works for me might not work for you.
Life can be cruel. There will be people in your life who won't be very nice.They'll tease you because you're different, or for no good reason.They might try to bully you or hurt you.
There's not much you can do about these people except to learn to deal with them, and learn to choose friends who are kind to you, who actually care about you, who make you feel good about yourself. When you find friends like this, hold on to them, treasure them, spend time with them, be kind to them, love them.
There will be times when you are met with disappointment instead of success.Life won’t always turn out the way you want.This is just another thing you’ll have to learn to deal with.But instead of letting these things get you down, push on.Accept disappointment and learn to persevere, to pursue your dreams despite pitfalls.Learn to turn negatives into positives, and you’ll do much better in life.
You will also face heartbreak and abandonment by those you love. I hope you don't have to face this too much, but it happens.Again, not much you can do but to heal, and to move on with your life.Let these pains become stepping stones to better things in life, and learn to use them to make you stronger.But be open to life anyway.

亲爱的塞斯：
你现在仅仅3岁，此刻你还不识字，更不用说让你去理解我接下来想在这封信里对你所说的话了。但是我已经苦思冥想了好久，关于你即将面临的人生以及我的生活，我反思我所学会的；思考一个父亲的职责，力图让你为未来岁月中即将面临的困难做好充分准备。
我希望通过分享一些我所学到的最好的道理来帮助你走好人生路。至于任何建议，且把它当作佐料，因为适合我的并不一定适用于你。
生活会很残酷。你的生活中一定会有并不友好的人。他们耻笑你因为你不同，或者没有更好的理由。他们可能会欺负你或者伤害你。
对这种人你除了学会和其接触无计可施，同时你也要学会择友，选择那些对你友善的，那些真正关心你的，那些令你对自己感到很好的人做朋友。当你寻找到像这样的朋友，就一定要坚守这份友谊，珍惜他们，花些时间和他们在一起，友善地对待他们并爱他们。
有时你会遭遇挫折而非成功。生活并不总会如你所愿。这是另一件你需要学会处理的事情。但你要挺住向前，而不是让这些事使你陷入低谷。接受挫败并学会坚持，不畏风险地追求你的梦想。学会把消极转化为积极，之后你就能做的好得多。
你同样会面临心碎时刻以及你深爱的人的抛弃。我希望你无须经历太多此类事件，但假如不幸发生了，再一次，除了慢慢愈合心中的创伤并继续你的生活，你别无选择。让这些痛苦成为你通向更美好生活的垫脚石，并学会利用它们让自己更坚强。但无论如何，都要张开双臂拥抱生活。
