Please check my first speach, thank you

I would like to ask you for check vocabulary and grammar for my speach. This is my first english speach, so I probably do many mistakes. Thank you for your help.

The speach:

Dear Toastmasters, I would like to introduce you myself. As you know my name is Jack. I was born in June in eighties in a small town near Szczecin. So the weather was very nice, but the times didn’t. I don’t remember many things from my childhood. Except two situations. First one, someday, when I was playing in sandpit the giant roster attacked me. OK, maybe not giant, but I’m sure that he was big. I even realized that I could run so fast. I learned then how to move horizontally. The second situation, was when my mother and I were on shopping. My mother went to the shop and I stayed in front of shop-window. Suddenly, the metal floor grill under my foot was collapsed and I fall down into the basement. I was in shock. When my mother left the shop and realized that I disappeard she panicked. In my lucky she heard my cry. It was time when I learned to move vertically.

When I was five or six and my sister was born, we moved to Wloclawek. Then I was learned how to receive the world by senses. I saw the beautiful bridge on Vistula river. My grandparents lived near railroad tracks so I always heard trains when I visited them. I felt cool smell of coffee raising up through the air from the local coffee roasting plant. I was falling in love then so I also felt first touch and I realized a taste of raspberry lipstick.

When I finished my high school I moved to Lodz City for studying computer science on university. It was year 2000, so it is very easy to count how many years I live here.
I like music. It is inspiring me. I remember a song that a lot has changed in my life. The title is “Forever Young”. Let me quote my favorite verse:

“It’s so hard to get old without a cause
I don’t want to perish like a fading horse
Youth is like diamonds in the sun
And diamonds are forever “

When I heard thes words first time I didn’t understand their meaning. I need time to understood. I asked a few questions for myself. How to live? What is the meaning of live? Now I know. In life, in my life, the idea is to be happy. I found these great manifesto on the net. You probably heard that words many times. But let me tell them one more time: “This is your life. Do what you love, and do it often. If you don’t like somethin, change it. If you don’t like your job, quit. If you don’t have enough time, stop watching tv. If you are looking for the love of your life, stop; they will be waiting for you when you start doing things you love. Stop over analyzing, life is simple. All emotions are beautiful, when you eat, appreciate every last bite. Open your mind, arms, and heart to new things and people, we are united in our differences. Ask the next person you see what their passion is, and share your inspiring dream with them. Travel often. Getting lost will help you find yourself. Some opportunities only come once, seize them. Life is about the people you meet, and the things you create with them so go out and start creating. Life is short. Live your dream, and wear your passion.” Good luck, don’t worry and be happy. Thank you for your attention.
