First notebook entry: Introducing myself

Hello my friends, I am from China, and my major is chemistry chemical engineering. In our my country, if your English is not good ,you won't get good chance in work and study chance into better schools or jobs if your English is poor. I don't think it think this is fair, but however ,I cannot change this phenomenon. I can only adjust myself to the situationfor that. I want to meet people from allover all over  from other place of the world too. I like philosophy, sports and many other things. However, and I always lose in sports, I don't know why.

I know there must be some wrongs are mistakes in my article.   Thanks for any modificationyou do. good luck to everyone. Thanks.

Your punctuation spacing rules are atrocious.  No blank before commas and full stops.  One space after a comma and two after a full stop.
