As humans we generate two outcomes and then experience the outcome of both realities, even though none of them are real. We vicariously live in these realities until all other thoughts collapse and you end up in the present moment.

Until reality is observed, both realities in our mind exist in the state of quantum 'superposition'. However, when you look the wave function, it collapses to deliver one reality.

As your mind prepares you for all outcomes, there is a lack of communication between your brain and you- which cripples your ability to enjoy the only truth and reality - the present moment.

Do not wait for your superposition to collapse.

The distinction between the past, present, and future is only a stubbornly persistent illusion. - Albert Einstein
