Thanks for the replies, I've been trying to do this and also continuous mindfulness (looking for weird things and being mindful kinda help each other simultaneously), it's still difficult to keep in mind though, especially when I'm working on the computer and have to focus, I find it very hard to divide my attention between work and mindfulness/awareness.
Also, I have an idea but it might be overkill.. which is, whenever you notice you've "tuned out", that you've been on auto-pilot for a while, ask yourself "am I dreaming?" and do a quick nose pinch RC. Now it might be overkill because the average person "tunes out" a lot throughout the day. I know I do. But I sometimes get mad at myself for not being able to stay tuned in for longer, it's so frustrating.
