Wojtek puts it quite frankly "If it wasn't for my youth openness my best years of professional development would never happen", so he was. One day at work, a guy from Norway showed up and talked about Facebook and LinkedIN, so he signed up. The other day somebody texts him on linkedIN "Hey, would you like to meet up in Warsaw?", so he went. That trip resulted in projects for Disney and Wrigley. When he asked "How is this possible to pull off jobs for such clients?" he heard "come to London, we'll see what else we can do". That's how Wojtek landed in a startup with a mission to create a sales tool that would integrate different sources of data and make predictions or what if modellers. That 10 year stint had been a period of extraordinary lessons in extremely stimulating environment. As Wojtek had the opportunity to work with high executives and board members of global corporations he took that chance to ask what enables them to do what they do the way they do it. This is how he learned the lesson of three fundamental traits of top managers: ability to ask and collect opinions, mindfulness and treating everybody as equals. That lead to powerful conclusion: "If we talk - we teach others, if we want to learn - we have to listen and ask right questions". As a result of being the dumbest in the room you can find yourself surrounded by people who you admire the most.

There is ongoing race of technologies and frameworks. Therefore, if you decide to enter this profession, your passion and business goals are absolutely the most essential. Find a specific area that you are passionate about, that may be finding new cure, fraud detection or whatever else. Find it, that will fuel your development. You should also be aware of wisdom trap, as it was in case of Steve Jobs and Segway. When Steve got into one of first Segway's pitches he heralded it as the most innovative product since creating a computer and that it will revolutionize mankind completely. His words opened wallets of investors, but Segway had never been close to revolutionize anything. The wisdom trap - people, influencers who were surrounded by innovation didn't even bother to check if that particular idea makes sense. That's why Wojtek advices to be open to question everything and verify ideas. Furthermore, he claims that learning to make mistakes and admitting failures is another essential lesson of his lifetime. The essence of data scientist's job is solving particular problems so never stop asking 'why'. He explain it this way: "when implementing machine learning solutions in business it is extremely essential to fully understand the problem we're dealing with. Therefore, you will make mistakes on your way to finding the truth which is hidden behind people and data".
