Keep them forever there

Keep them forever there 

 Build for yourself a strong box,
Fashion each part with care;
When its strong as your hand can make it,
Put all your troubles there;
Hide there all thought of your failures,
And each bitter cup that you quaff;
Lock all your heartaches within it, Then sit on the lid and laugh.

Tell no one else its contents,
Never its secrets share;
When you've dropped in your care and worry,
Keep them forever there;
Hide them from sight so completely
That the world will never dream half;
Fasten the strong box securely -
Then sit on the lid and laugh.
