In those last 14 months I did once.
If the contest doesn't appeal to me, I don't. Many contests out here have nothing in common with my niche topic. Writing many Hubs in one time is not my passion either.
Cooking contests are the worst for me here. I like food. I like to go out for diner but preparing food is not my hobby at all.
My hobby is to write, to create awareness about mental illnesses and to be inspiring to those who read my Hubs.
So far I haven't seen contests that provoke me to join and spend a lot of extra time here.
