Reason really isn't that complicated to use... Samplers (the panel things) play their sounds and the effects (other panel things) modify the sound. Just play around with it, play some of the demo songs and mess with the effects.
In another vein, toast's and Meltdown's comments are absolutely (and obviously) true! I play bass guitar and Arabic `ud (stringed instrument like a lute), and I'm not amazing, but I practice usually an hour a day per instrument. I love to practice, I don't find it taxing or arduous at all. Proficiency takes practice and dedication, if you want to make music and do it well, just work at it, and you'll find your talent...you'll find that playing around in Reason will become more and more intuitive and you'll lose hours sitting in front of it, tweaking everything to your masterpiece.
