Build for yourself a strong box.Build each part with care；

When it strong as your hand can make it，

Put all your troubles there.

Hide there all thought of your failures.And each pain that you take；

Lock all your heartaches in it，

Then sit on the lid（盖子）and laugh

Tell no one else what's inside，Never share its secrets；

When you've dropped in your care and worry，

Keep them for ever there.Hide them from sight（视野）so completely；

That the world will never dream half；Cover the strong box safely，

Then sit on the lid and laugh.
