Experience is a good teacher, <br />Costly though it is. <br />Adversity is a better teacher, <br />Expensive though it is. <br />Failure is the best coach <br />Too late though it is. <br /> In all instincts rule. <br /><br />Rm.Shanmugam Chettiar.<br /><br />http://www.poemhunter.com/poem/to-teach-the-instinct/
