alot of stuff you can read about meditiation is hooey, but practicing mindfulness and letting thoughts pass you by is a useful skill to practice. it takes some work, especially if you have a focus/anxiety problem. dont let your mind dwell on a thought, but dont push it out of your head, just “finish the sentence” as it were and move on to the next empty moment. it helps some people to visualize wiping a white board, smoothing sand, calming waves/ripples, etc.
