Depends what part of the process you like. Some people like to be very meticulous in their hobbies, and somewhat of a perfectionist. That rarely exists in a professional environment, where everything is based on getting projects out the door, on schedule and on budget.

I actually like banging out projects quickly, so the professional life of my hobby suits me well (woodworking). I love pounding out big mortises with a sledgehammer, planing big boards and watch chips go flying. I hate fiddling with joinery and slowly fitting them for 10 minutes (slowly learning how to do them faster). For other people, joinery is their favorite part.
