this is my first book, "เรียนรู้ด้วยใจอย่างใคร่ครวญ" which just came out a few days ago. it's a compilation of the articles i have written in the past 4-5 years. if you're still wondering if i'm sane or not, you might want to buy one for yourself and the other one for your friend. it's published by "สวนเงินมีมา".
