At the end of November I am launching my book: Sales, Honest & Relaxed.

I have more than 25 years of experience in sales. Always from my own company, selling to organisations like Google, Samsung, Microsoft and ING, all over the world.

What I have seen in all those years is that sales is often not honest. That a lot of tension and forcedness creeps in. That pressure comes from the finance side, because it has to happen. And then you get exactly the opposite result of what you want.

My biggest insight: honest and relaxed selling works by far the best in the long run, for the best results.

And how do you do that? That is what this book is about.
