Important words in Human Relations

This was told by my trainer and was also found in a book by John C. Maxwell 'The Power of Influence'.

6 most important words 'I ADMIT I MAKE A MISTAKE '.
5 most important words ' YOU DID A GOOD JOB' .
4 most important words ' WHAT IS YOUR OPINION' .
3 most important words ' IF YOU PLEASE...'.
2 most important words ' THANK YOU'.
MOST important words ' WE'.

Last but not least, THE
LEAST IMPORTANT WORD 'I'.

Think of it, how often does we use those word, 'I' may be the most common used. Its time to reflect and think. =)
