Dealing with something new demands a lot of energy. On top of the rational side of the new role, there is an iceberg of social learning and anxiety. You are not only finding your space in this new tribe but crafting it in every new interaction. Give yourself time to fully immerse in this challenge. In my opinion, is more important to use the after hours to take care of your personal life and build mental resiliance. In time, your curiosity for new topics will surface once again.
