Well i started 4 years ago. I started with 2 minutes every morning and at night. Night session went uo gradually. I count my breath on exhales to 4 and restrat. And when your mind wounders try and bring it bqck and center and continue the breathing. I was taught when you meditate its best to calm the mind but the mind does wonders off so try to breing it back to the center of nothing and breath.. i followed this and 20 minutes was a whole trip 

I also learned this in drug rehab and it has help throughout me stay away from drugs actual hard drugs.. 

But there is no wrong way to meditate well the way is dou g 1 minute and saying nothing happens because at first i thought this and played myself
