A system for directional drilling and related method of use is described herein which utilizes a drillstring suspended within a wellbore with an MWD and downhole turbine or motor connected adjacent a drill bit on a lower end of the drillstring, and with a top drive and/or rotary table connected adjacent an upper end of the drillstring. Within the method, desired limits of drilling associated parameters are inputted into a memory associated with a programmable digital computer. While drilling the wellbore, transmitted values of the drilling associated parameters are inputted into the memory. If the transmitted values are outsude of the desired limits, necessary adjustments are calculated and then made to weight-on-bit (WOB), RPM and/or drillstring azimuthal orientation to bring the transmitted values within the desired limits.
