I wont lie, I have fallen victim to many meditation misconceptions like "I'm not supposed to think" or "meditation means I have to be passive and emotionless" and even "when meditating I have to fall into a trance like state" after a year I realised this was just me falling asleep lol.
I have read a few books on mindfulness meditation and the instructions all very simple but still I find myself wondering "am I even doing anything at all" and feel like I have to really be putting in alot of effort to know I'm achieving something.
I find because I can't actually get someone actually in my head showing me how to do it I can never truly know if I'm doing it right. For myself, I enjoy the way Trungpa and Pema Chodron teach meditation, which is to note when you find your thoughts running away as "thinking" and then gently return to your breath with no judgement. If you sit in Meditation and permit things to arise, pass and fall away unhindered, then the Mind Comes Home, and Calm Abiding is present.

What resonated with me was what he said about breath being subtle and I can see how even concentration on that you can lose yourself in the rhythm.
What I really enjoyed though was 10% happier by Dan Harris, I really liked how mindfulness came from the point of view of a very western skeptic. Not in any mystical sense or anything, just that instead of using meditation to gain insight or whatever else, I meditate to recharge. Jumping into conclusions, and giving recipes for proper practice, often proves to be misleading. I've been meditating for 5 years now and there are still difficult days when my thoughts are running amuck and I spend an entire half hour telling myself "thinking, thinking, thinking" over and over again.

If he takes you seriously, he will try to validate his meditation, checking if his mind came home into calm abiding.
