 So you need also to see at some point of time if your value proposition is not presenting in the way that you were expecting it. You need to check if all of the assumptions that you are putting in place with your plan and with your positions if they still fall and if markets move in the meantime and if markets move you might need also to consider pivot. And this is something that's usually very hard to do and it is also one of the things that make you a really great entrepreneur when you know when to pivot or when to be persistent with your current idea. And then if you are lucky you didn't need to pivot. You built a product that resonates and a product that people like but then what's super important with a product is a life cycle. It's also life being. At some point of time you also need to see when is the time to also put that product at sleep and this continues. So it's also with a number of startups that became afterwards successful companies because they were sticking too much with the certain things that they were working that they worked as a company but they insisted on a certain view and certain vision and they didn't respect this product life cycle and then they failed their lives. Looking with teacher phones company that I mentioned that is on Nokia and others they didn't want to retire those months. It was about the time to retire them and to jump completely onto the smart phone. And then you see today they are just part of the technology history and soon you will see those products more in the museum more. Persistence. So this is the one like as mentioned before that is a bit contradicting the people. So there you need to make up your mind whether you are pivoting and you go for it or you are persistent with the stuff that you are building. So whatever you do, whatever you build, it's not a question if you are going to hit the wall. It's only a point and only question there when you are going to hit. And there when you hit it and when you hit it really hard you need to come back to your initial plan. You see again people and all of the other stuff. Evaluated and it is really there as it was from the beginning where you need to get additional strength, additional power and move further. With us at the theory of back at the time we were moving 1% of tele-nord in common like the Deutsche Telekom in Germany. We were moving 1% of their subscriber base on a fixed telephony that was so likely to come. And that was the rate that was frightening. So of course they don't stand still. So first thing is like they try to slow down all of the administrative arts. How many users you can move per day and make it harder for you. You find institutions and you take them to the courts. You push them, you move them, you are going further and then everything looks quite good. And then all of a sudden comes a lawsuit. Massive lawsuit and then it appears that the lawsuit comes from the regulator but as you get the details of that lawsuit you see that the accountant is staying behind you. And then you know that night you don't sleep. When you are reading about it you see just like a massive cost and you see the moment that can kill your small company that is growing quite nice, has a fantastic enthusiasm and everything looks like it's a boring apart. But then you don't make any decisions after that night of no sleep. Sleep another night. And evaluate. Again, all of your points and everything which you were reading and you will find a way to overcome it. And it was the same thing with us. We won at the court the first instance. We won again at the second instance. But that's the first thing what they need to check before they go for the next points to put investment in your great startup. And then if answer is negative then they kill a little bit more and then who is against you? Stay. Stay away. So that was also why they were staying away from us and then that was also why those investors that came at that time in failure they made 60 times return or 6,000% of return up to today together with dividends on the current share price. But no bad thing is as bad as it looks like. On the first you need always to look things in a certain cases it won't work. But I think that those are rather exceptions. So their persistence is definitely one of very important virtues for you as an entrepreneur and for you as a startup founder or one of the early startup employees. So those are some of the references to the story and then what I love to joke is that there is one more P and you know when you hit the mid-life crisis and when you do reasonably well with the startups then it's first privacy but I'm going to skip that one because there is also even more fun about this one I would be really glad to talk with you afterwards but the other more fun P is missing here It's one of the great German brands and that's a Porsche. Everyone who would formally recommend you once when you make it if you are hitting close to the mid-age get yourself a one even if it looks like cheesy and if it is too much of a silicon valley thing it is also quite nice and quite fun things to do and I wish you all getting a one if you want one or if you don't want to get in there whatever P excites you Thank you
