Quote by William Arthur Ward (1921-1994)

• The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.

• If you can imagine it, you can achieve it. If you can dream it, you can become it.

• If you can imagine it, you can achieve it.
  If you can dream it, you can become it.

• We can learn much from wise words, little from wisecracks, and less from wise guys.

• The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.

• It is wise to direct your anger towards problems -- not people; to focus your energies on answers -- not excuses.
