I have to write a Shakespearean Sonnet?

I know it has to be 14 lines, and each line needs 10 syllables. I also know it has to be in the rhyme scheme: ABABCDCDEFEFGG but it is very hard! Can someone help me out? I was thinking about writing it about growing a flower or something, particularly a rose, but any subject matter will do. Can someone please help me get started? Thanks! And happy new year!
