Two frogs
Two young frogs fell into a bucket of milk. Both tried to jump to freedom, but the sides of the bucket were steep and no foundation was to be had on the surface of the liquid.
Seeing little chance of escape, the first frog soon despaired and stopped jumping. After a short while he sunk to the bottom of the bucket and drowned.
The second frog also saw no likelihood of success, but he never stopped trying. Even though each jump seemed to reach the same inadequate height, he kept on struggling. Eventually, his persistent efforts churned some milk into butter. From the now hardened surface of the milk, he managed to leap out of the bucket.
Those who don't give up and persevere
may be in for a pleasant surprise!

What is a mainframe?
Mainframes (often colloquially referred to as big iron) are large and "expensive" computers used mainly by government institutions and large companies for mission critical applications, typically bulk data processing such as censuses, industry/consumer statistics, ERP, and financial transaction processing.
The term originated during the early 1970s with the introduction of smaller, less complex computers such as the DEC PDP-8 and PDP-11 series, which became known as minicomputers or just minis. The industry/users then coined the term "mainframe" to describe larger, earlier types (previously known simply as "computers").
Description
Modern mainframe computers have abilities not so much defined by their performance capabilities as by their high-quality internal engineering and resulting proven reliability, high-quality technical support, top-notch security, and strict backward compatibility for older software. These machines can and do run successfully for years without interruption, with repairs taking place whilst they continue to run. Mainframe vendors offer such services as off-site redundancy ? if a machine does break down, the vendor offers the option to run customers' applications on their own machines (often without users even noticing the change) whilst repairs go on.
The robustness and dependability of these systems has been one of the main reasons for the longevity of this class of computers, being used in applications where down-time would be catastrophic. The term Reliability, Availability and Serviceability, or RAS, has become a marketing term used to denote this robustness. This robustness is often the argument used against replacing mainframes with other types of computers.
Mainframes often support thousands of simultaneous users who gain access through "dumb" terminals or terminal emulation. Early mainframes either supported this timesharing mode or operated in batch mode where users had no direct access to the computing service; it solely provided back office functions. At this time mainframes were so called because of their very substantial size and requirements for specialized HVAC and electrical power. Nowadays mainframes support access via any user interface, including the Web. (An IBM mainframe was the first Web server anywhere outside Europe.) Blade servers and rack servers, rather than mainframes, are now increasingly requiring exotic cooling technologies and take up far more data center floor space.

Refusing to Accept Failure
Sir Edmund Hillary was the first man to climb Mount Everest. On May 29, 1953 he scaled the highest mountain then known to man-29,000 feet straight up. He was knighted for his efforts. He even made American Express card commercials because of it! However, until we read his book, High Adventure, we don't understand that Hillary had to grow into this success. You see, in 1952 he attempted to climb Mount Everest, but failed. A few weeks later a group in England asked him to address its members.
Hillary walked on stage to a thunderous applause. The audience was recognizing an attempt at greatness, but Edmund Hillary saw himself as a failure. He moved away from the microphone and walked to the edge of the platform. He made a fist and pointed at a picture of the mountain. He said in a loud voice, "Mount Everest, you beat me the first time, but I'll beat you the next time because you've grown all you are going to grow... but I'm still growing!"

You never really lose your Value!
A well known speaker started off his seminar by holding up a $20 bill.
In the room of 200, he asked, "What is this piece of paper & is it worth any thing ?"
"It is a $20 bill, encashable in international & national markets for it's quoted value ?" replied one of the many participants who raised their hands.
He proceeded to crumple the dollar bill up using both his hands till it became a bundle of wrinkled paper.
He then unfolded it again and making an unsuccessful attempt to keep it straight he asked, "Would you still be able to negotiate it for it's quoted value?"
" Yes !!" was the echoing reply from the participants.
"Well," he said, "Looks like I haven't done enough ! What if I do this?" And he dropped it on the ground and started to grind it into the floor with his shoe.
He picked it up, which was now all crumpled, dirty, defaced & not easy to recognise from a distance. "Now will some one like to trade it for its quoted value?" Many hands went in the air.
"I think this piece of currency is still holding its quoted value" replied a participant in a slightly unsure voice.
"This bill can still fetch goods worth 20 Dollars" said the other participants. Every one agreed.
"My friends, there is a very valuable lesson in this exercise that we are just through with. It may have appeared to some of you, that I was able to deshape, deface, mutilate & alter the $20 bill during the process as the effects were quite visible".
"However, No matter what I did to this piece of paper, you still upheld its negotiability because you were sure in your mind that my actions did not actually decrease its value. It was still a currency note worth $20".
"Many times in our lives, we feel like as if we are dropped, crumpled, and ground into the dirt by the decisions we make and/or the circumstances that come our way. We feel as though we are worthless. It may also appear to onlookers as if it has really happened to certain extent. But no matter what has happened or what will happen, please remember you never lose your "Value"."
Values that you cherish are indeed devoid of worldly disturbance & always are your saviour.
