Straight on

I've realised that things that potentially might change my life, small or big, they happen in discrete packets of happenings called quanta.

No, I was just joking. Physics-sense huh? (As opposed to common-sense)

I've realised that things that potentially might change my life, small or big, happen spontaneously (No, not Nuclear Physics here). Very very spontaneous.

Now after cancelling the jokey stuff out:

I've realised that things that potentially might change my life, small or big, happen spontaneously, sometimes happen so quickly, that I don't know what to exactly do when they happen, and sometimes can't recall what I did when they were happening.

So that's life for me.
