A stamp is to many people just a slip of paper that takes a letter from one town or country to another. They are unable to understand why we stamp collectors find so much pleasure in collecting them and how we find the time in which to indulge in our hobby. To them it seems a waste of time, a waste of effort and a waste of money but they do not realize that there are many who do buy stamps, many who find the efforts worth-while and many who, if they did not spend their time collecting stamps, would spend it less profitably. We all seek something to do in our leisure hours and what better occupation is there to keep us out of mischief than that of collecting stamps? An album, a packet of hinges, a new supply of stamps, and the time passes swiftly and pleasantly.
Stamp-collecting has no limits and a collection never has an end; countries are always printing and issuing new stamps to celebrate coronations, great events, anniversaries and deaths. And the fascination of collecting is trying to obtain these stamps before one's rivals. Every sphere of stamps-collecting has its fascination-- receiving letters from distant countries and discovering old stamps in the leaves of dusty old books. A stamp itself has a fascination all its own. Gazing at its little picture we are transported to the wilds of congo, the homes of the Arabs, and the endless tracks of the Sahara desert. There is a history in every stamp. The ancient Roman empire and the constitution of America, India's independence and the allied victory, are all conveyed to our minds eye by means of stamps. We see famous men, pictures, writers, scientists, soldiers, politicians and famous incidents. Stamps, so small and minute, contain knowledge that is vast and important.


PRECIS: Stamp seems to be a little piece of paper but in the eyes of stamp-collector, this piece is precious, a companion of his leisure times. Stamp-collector, collects different stamps of various countries and through them visit the whole world in a glance, from Africa to US & from India to Europe. There is no end to this hobby as different countries consistently issued stamps on their various special events.

TITLE: Hobby of Stamp Collecting

just a quick remarks
you have started with same way and with same words as original passage contains.
secondly use pronouns which reduces redundancy.

last but not the least, read the last three-four lines of original passage, you missed an important point i.e. stampt though a little piece of paper but it conveys a glorious history of a nation.

note; i just skim it ok, didn't see it critically.
best of luck
