From a Neurodevelopmentalist and TKM student
I saw a 15 year old young man last week.  He has always had been extremely negative and moody. I can not think of anything good he has ever said or a time when he smiled.
Four months ago I finally convinced him to try the Median Self Help Sequence.    The moment I saw him I knew he had been doing TKM® the past four months.  It was so visually apparent.  His skin looked good, he had better color, and there was almost a "glow" from him.  I know a fifteen year old boy wouldn't appreciate being said he glowed, but he did.  His entire posture was improved, as he stood taller than I've ever seen.
I asked him if he was doing TKM®.  He smiled... yes a smile..., and said yes.  I asked him how much and he said most every day.  I asked him if he was happy.  The question wasn't needed, it was so apparent.  I just wanted to hear it from him.   He got this real sheepish look and said yes!  He was really happy.  This was so exciting!
Changes during the past four months reported by his mom:
more maturity
more responsible
happier, very little negativity
socially doing better
getting along well with his younger sister - they have never gotten along and have had problems
better emotional balance
major reduction in overreactions
What a great thing for this young man and his family! 
All this improvement just by doing the Median Self-Help Sequence on a consistent basis.
