Not all bullets are a single dash. All of your main points are single dashes. Sub-points are two dashes and sub-points of the sub-points (aren't used often) are three dashes.
There should be more than one main points.
For example if I read Harry Potter, I might have the following main points
1 He is a wizard
2 His friends are important to his success
3 His enemy is Voldermort
my sub-points might be:
sub 1 he displayed magical powers from an early age
sub 2 Hermoine and Ron helped him defeat Prof. Squirrel
sub 3 Voldermort killed his parents
a sub-sub-point might be
sub-sub 1 he made glass disappear at the zoo
Follow the example found in the tongue and quill
I hope that this helps.
