"ALWAYS BE APT TO LEARN FROM OTHERS!" 

Sometimes GOOD ADVICE is NOT in telling you what THEY'VE DONE but what they SHOULD'VE DONE! A WISE person will share their mistakes with you in hopes of you NOT repeating them. Only a FOOLISH person learns from mistakes they were FOREWARNED NOT to make! 

FOR A WISE PERSON LEARNS FROM OTHER PEOPLE'S MISTAKES!"

Proverbs 19:20 KJV

Hear counsel, and receive instruction, that thou mayest be wise in thy latter end.
