I tried to diversify my portfolio too, but I quickly realized that it makes things even worse for me. I tried a deep dive into AI with only a limited success. Also employers are somehow not happy if they see you were working on one thing for 10 years and gained some reputation and then suddenly switched directions. But they also want that you to switch directions 🤷🏻♂️🤦♂️
Good point with the teammate. Actually I would love to join a small startup where you‘d work in pairs on small pieces of a big project. But I don’t find any in the EU.
