Always desire to learn something useful.
Sophocles
Useful....
It is such a useful term
As long as we realize that useful and practical do not have to be the same thing
Balloons are very useful
They make my grandkids smile
Dandelions are useful
They give you wishes to blow in to the wind
Francis Bacon said:
Choose the life that is most useful, and habit will make it the most agreeable.
