By: Berthold Gunster“Transformative.”—Greg McKeown, New York Times bestselling author of Essentialism and Effortless
Change your mindset from problem-focused (“yes, but”) to opportunistic (“yes, and”) using omdenken, the Dutch art of flip thinking—from the bestselling author and founder of the omdenken philosophy.
Imagine this: You’ve got a great idea, and all you hear are the yes-buts.
“Yes, but that’s been tried before, and it didn’t work.”
“Yes, but shouldn’t we just let it sit for a while?”
“Yes, but what if it doesn’t work?”
Published in English for the first time, this international bestseller introduces the power of omdenken—or flip thinking—to transform stuck-in-the-mud, pessimistic thought into an inventive, curious mindset, so you can stop saying “yes, but” to life, and start saying “yes, and.”
In this riveting book, Berthold Gunster presents fifteen strategies to transform your thoughts away from limitations and negativities and towards possibilities and opportunities. From disrupting (turn all the rules upside down) to flaunting (play up what you want to hide), from importing (get the enemy on board) to amplifying (do more of what works), Gunster’s strategies and stories will have you approaching even the most challenging problems—whether an annoying neighbor or an angry colleague or an unhappy partner—in a whole new way.

Perfect for low dose, great price
On my second bottle, great product for the cheap price, lasts almost a year. Hard to find in this low dose. I personally find low dose melatonin to work better than the higher amounts. It’s the sweet spot.

Knocks me out cold
I wish I could easily find a lower dose, but this works.
Take one about 30 mins before I want to sleep and when I fall asleep I don't wake up in the middle of the night. I normally have insomnia but one of these generally gives me 9 hours of sleep.
It doesn't ALWAYS work (I have health problems that can keep me awake) but instead of 5-7 hours sleep I am consistently getting around 9.
The only problem is I'm groggy in the morning. But I feel a lot less haggard and anxious in the morning now so I think I'll be continuing with this.

Very good product
These melatonin pills work. I bought them because sometimes I'm so stressed or pressured by everyday life that I find it hard to fall asleep. I don't use them every day, only when I really can't sleep and it's very late. I must say that this pill doesn't knock you out completely. I liked that. You fall asleep slowly, and the next day you don't feel groggy or like you've had too much to drink. It's a great product!
