My grammar is terrible

Hello everyone. I just don't know what makes my English so different from the native speakers. I really would like to improve my English. Maybe even it doesn't sound like a native one, but I need to be a master at it. Please correct this very first post; especially the grammar.

Thanks.

"...I need to be a master at it" is more natural as "...I need to master it".

Practice makes perfect. You'll get better :-)

My grammar is terrible.
