Tell me how does one forget and relax

For those of you (I'm one of you too) that check the cm , cp , temp, take opk etc. . And are so in tune with what your body is doing every single day , how do u forget about ttc and relax how is that possible after knowing what's going on and what to feel for what to look for .. I try and try and can't just forget its impossible and so frustrating. I've read to relax dnt think about it dnt check for this or that .. and it will happen . . Easier said then done :"(
