Human Factors
Departing C83 Byron IFR; I deviated from the ODP because I had relatively good visual with the ground and proceeded on course to destination.  The visibility was such that they were doing skydiving at Byron.  I now realize that ATC doesn't know what my conditions are and that I need to stick to the plan so as not to increase their workload to handle my errant ways.
Single pilot reported deviated from IFR clearance by flying direct course to destination instead of following the ODP on departure without ATC authorization.
