Lifting the pressure of 'having to shift'

What I mean in the title is that I think I'm pressuring myself too much to shift, so now it feels like a big deal to me. I think thats why they say that you need to 'let go'. I've also seen other people saying that when they had their shifting experience that they told themselves that it was okay if they did and okay if they didn't shift. So maybe that's part of the key to actually shifting is having low pressure stakes and letting go.
