About the author

After being successful at the age of 20, I failed flat out and fell into debt. Through thousands of hours of trial & error, filled with embarrassing, painful and uncomfortable moments, I discovered what does work.How did I do it? Let’s just say that I started to do the exact opposite of most people. When most people started watching television, I read a book and started testing it. I’ve learned quite a lot in those 15 years.

Our Mission

My mission is to remove the dumb-tax in the world. After I made a lot of bad choices I had to pay a massive dumb-tax. Those lessons helped me to make less dumb choices. 

You don’t have to make a lot of great decisions, you just have to make less dumb choices
