Hide it from everyone except your close friends that might read it. (One of my friends reads mine)
Make sure you always have paper to write an idea down. (You never know when you will think of one.)
(Ugh I haven't been on wattpad in a while.)
Anyway, do you write fanfic? If so where i.e. at home, school, etc.
I write it at home and school that is it but it does depend on which fanfic.
