Why can't i do this

These blogs are so hard for me to write I sit down trying to find something interesting for me to write about and nothing ever comes, so I end up writing a tiny little paragragh about my sports life basically. I never remember to do these until like 11 at night so i never use the correct punctuation. This is something I am not good at but i know my classmates blogs are really good and i find it more fun reading theirs than typing my own.
