I notice this with typing. I have no idea which finger hits which key on my keyboard. If I make a mistake and then consciously focus on the characters instead of the words my typing slows down and lacks fluidity.
If you believe in determinism then we are essentially just spectators of our own life. We just don’t realise it. We think that because we have made choices it was a possibility that other outcomes could have arisen. We don’t acknowledge that everything was always going to converge at this single point i.e everything was always going to be as it is now.
