Quantum mechanics is just completely strange and counterintuitive. We can't believe that things can be here [in one place] and there [in another place] at the same time. And yet that's a fundamental piece of quantum mechanics. So then the question is, life is dealing us weird lemons, can we make some weird lemonade from this?
Radical acceptance rests on letting go of the illusion of control and a willingness to notice and accept things as they are right now, without judging.
