It is only mindless if you do it mindlessly.
There are so many avenues of escape, by doing what you are already doing, by just paying attention.
For example I made multiplayer video games sour for myself by being overly competitive, going in with expectations, not going with the flow.
But if you leave expectations aside, just really BE in the moment, and are aware, you can enter flow.
Try to flow always, and remove wrong motivations from your mind.
Then you can be in the now always.
Practice makes perfect.
