I'd say the best trick is to dip your hands into lots of different styles, that's what I've done the last 10 years. It keeps me motivated, and I find new ways of doing things and I can apply that experience on my regular Techno.
Producing some Dubby Techno or slow beats with electronica elements or very melodic music is very meditative for me and gives my mind peace, gives me energy to keep on slammin with those harder beats.
