Eliminating stress while trying to conceive...

What are some of your best ways to relieve stress? 
I work a ridiculous amount of hours at work and that cannot change. I own my house solely and am the primary "breadwinner" in my family (none of this I am complaining about or would like to change). Just saying, stress in my life, and anyone else's life, is unavoidable. Looking for some ways to unwind and relax and I assume much of my difficult getting pregnant for the first time is linked to stress. (A little background: cycles are, and always have been, regular, hormone level are all normal, and normal exams every year since I turned 18). Any suggestions are greatly appreciated!
