publish 3 novels or more

i have 2 novels of a fantasy trilogy completely plotted out in my head; the 3rd one has a beginning but not an end. i also have 3 more sci-fi/fantasy novels pending (the pairling, about dreams and moments of the master) and another 2 contemporary-style novels (something of love and the interdependence of souls) waiting in the wings.

i just need to get myself to finish the 2 and start the rest. i’m not lazy or unmotivated; i’m literally scared of it.
