A text of Public Speaking - collecting stamps

Please help me to check if I'm incorrect, thanks!!

Good morning, everyone. Today, I'd like to share with you all about my hobby. During my schooldays, I liked collecting stamps. It's not an interesting hobby, but it's an exciting way to learn about geography, history and different cultures of countries.

If you're interested in coleting stamps, there are many steps you need to know. First, you need to decide what kind of stamps you are going to collect. Some may collect stamps of particular countries, one colour or different shapes you want.

Of course, you need to know where to acquire stamps. Normally, I got them by exchanging with friends. Sometimes, I bought them from the stamp dealers.

Once you got stamps, you could sort them according to country of origin, shapes, issue of years, animals, plants or whatever that you like to choose. By the way, you need to mount them in a good stamp album. Get the best album you can afford.

So I would keep them for the rest of my life. Thank you.

P/s: I felt it is not good for the conclusion, anyone can give me comments?
