Eli, Your not setting yourself up to fail.
Think about it like this.. If you do slip along the way then you will have a bigger challenge to beat next time, but think about how awesome you will feel when you have beat it.
You can also have treats, like when you make it day 10 give yourself something you know you will enjoy. (Not sh related)
Something to look forward too.
EDIT: Day 8 for me.
