The very first question is why do you want to meditate in the first place?

If...
"I want to quite my mind."
Good luck with that! Trying to quite the mind just makes it louder. Or even worse, throwing trash in the closet until it piles up and you're living a lie and going crazy. Our minds, considering that you are a human too, is not meant to be quite. It's more like a tool that evolved to sense and experience abstractions. Have a bunch of stuff in your mind? Too much to handle? Sit down, do nothing, feel everything and cry it out. Why? From my finite observation, sitting down, doing nothing, feeling everything and crying it out, is to allow you to slowly and gently follow the threads of thoughts, memories, and emotions, to find the mental kinks within yourself and be able to come to terms and integrate it into your being. Sometimes it's joyful, other times you will enter to dark places that will give you the temptation of getting up and doing something about it. Don't. We know what it feels like. It hurts, bad. But you must sit still and feel it out. That rash decision will only make things more painful. As long as you practice sitting down, doing nothing, feeling everything and crying it out, the mind doesn't become something you fight to shut up, but instead something you roll with.

"I want to be more mindful."
Why? Do you have a disciplined mind that can be concentrated to a single point? What good will it do to let it run wild without knowing how to get a grip on it in the first place. What will you do when you are diving down the pit of psychosis at 50000 mph? Can you snap out of the signs that lead there? Like the warping of the visual field? The spiral into vexing confusion that blurs the senses? Western new age hip plastic spirituality messed up bad trying to make mindfulness/vipassana meditation as the gateway to everlasting inner peace where the gods/daemons/demons/buddhas/devi/[whatever higher or lower dimensional beings here] fart the scent of flowers upon our noses and everything is all well and fine until you circle back to the beginning, again and again and again, and again. And again. And maybe this app that told you that you meditated for 20 minutes and gave you an award badge like a treat to a dog for doing so well. Then the thought pops up if you are even doing mindfulness properly, and another, and another, and another. You wanted to be mindful, you ended up confused instead. How about doing the exact opposite? Concentrate on that pen right next to you. With your entire being. Then come back to mindfulness. You'll notice single pointed concentration and mindfulness leads to the same place. But samadhi meditation is easier to practice for someone that didn't grow up with Southern Buddhism. Since it's only relaxed concentration. But it builds the necessary skill of being able to tug the leash when the mind is running too loose.

In simple terms from this fleeting being tapping away, meditation is the practice of bringing our identification aspect of ourselves beyond our minds and back into our senses to have an observation without an attachment to the preconceived notions that come up and layer upon our direct experience. Thoughts and concepts are a There-ness within the Is-ness of what we are experiencing here and now. Meditation is to strengthen this mode of awareness.

Disclaimer. I'm not a certified anything. Just a practitioner. Never met any of my teachers beyond the books and talks they created. Mindfulness meditation isn't for everyone, you want inner peace go do something else that won't make you deal/play with the worms in your mind on solo mode with a manual with a bunch of holes in it.
