chapters 3 and 4

After reading chapters 3 and 4 i felt lost so i had to go back and reread them. I think Im starting to understand that it is a process . You have to take ceratin mental steps to begin .i learned there is a way to begin as far as your thoughts. like, what questions one should ask themselves before you begin to write . How you should just jot everything down that comes to mind .I wasnt quite sure how many sentences it takes for it to be considered a paragraph . Im still confused and i hope i get it before the semester is over i just feel like its alot but im sure its not. Once i get it and fully understand the process im hoping ill be fine
