To write another more constructive post:

Focusing is a process that you can do as ritual that has a lot of scientific evidence behind it and that is recommended by CFAR. Understanding the steps isn't trival but there are people in this community who managed to understand it from writing material and/or the audiobook.

Having data is very useful. Heart Rate Variance is a very useful metric to measure and to learn to control. See http://www.sweetwaterhrv.com/SweetBeatHRV.shtml . It's worth noting that while the Mio watch claimed to measure with EEG accuracy it doesn't and you rather want one of the heart rate measurement devices recommended by sweetwaterhrv even if you use a different software than theirs.

Especially if you meditate without a teacher as guidance, having technology as guidance makes sense.

There a new device on kickstarter to measure breathing: https://www.kickstarter.com/projects/1488696076/sendinaden-smart-mask/comments
